A stepper motor drives the piston via an eccentric. Advanced software algorithms control motor speed based on piston position, achieving rapid fluid intake and smooth, constant fluid delivery while minimizing pulsation. The optional damper can further reduce pulsation.<\/p><p>Ball and seat inlet and outlet<i> <\/i>valves ensure precise metering. The suction the piston retracting creates to refill the piston chamber pulls the inlet ball off the inlet seat, allowing fluid to travel through the inlet check valve. Simultaneously, the outlet ball is pulled back onto its\u2019 seat, preventing fluid from exiting the piston chamber. During the delivery portion of the piston\u2019s duty cycle, the inlet ball is pushed back onto its\u2019 seat as the piston moves forward, preventing fluid from traveling back to the pump reservoir. Simultaneously, the outlet ball is forced off its\u2019 seat, allowing fluid to exit the outlet valve. For the valves to operate effectively, a pressure differential of at least 25 psi is required on the outlet side of the pump.<\/p><p>The pump\u2019s flow rate is set directly in mL\/min. using the keypad or remote control. Flow rates are determined by piston displacement (diameter and stroke length) and motor speed.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t<details id=\"e-n-accordion-item-2122\" class=\"e-n-accordion-item\" >\n\t\t\t\t<summary class=\"e-n-accordion-item-title\" data-accordion-index=\"3\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-2122\" >\n\t\t\t\t\t<span class='e-n-accordion-item-title-header'><div class=\"e-n-accordion-item-title-text\"> How do l choose an Optos Series pump? <\/div><\/span>\n\t\t\t\t\t\t\t<span class='e-n-accordion-item-title-icon'>\n\t\t\t<span class='e-opened' ><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-minus\" viewbox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h384c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t\t<span class='e-closed'><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-plus\" viewbox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H272V64c0-17.67-14.33-32-32-32h-32c-17.67 0-32 14.33-32 32v144H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h144v144c0 17.67 14.33 32 32 32h32c17.67 0 32-14.33 32-32V304h144c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-2122\" class=\"elementor-element elementor-element-33ae790 e-con-full e-flex e-con e-child\" data-id=\"33ae790\" data-element_type=\"container\">\n\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-2122\" class=\"elementor-element elementor-element-7da0b65 e-flex e-con-boxed e-con e-child\" data-id=\"7da0b65\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-5eb7ed2 elementor-widget elementor-widget-text-editor\" data-id=\"5eb7ed2\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>We recommend selecting a pump that typically runs in the upper half of its flow rate range for the best pump efficiency.

Some of our customers use the pump for hydrocarbon catalyst research, petrochem pilot plants, small-scale reactors, corrosion testing, hydraulic oil, and water\/solvent injection.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t<details id=\"e-n-accordion-item-2125\" class=\"e-n-accordion-item\" >\n\t\t\t\t<summary class=\"e-n-accordion-item-title\" data-accordion-index=\"6\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-2125\" >\n\t\t\t\t\t<span class='e-n-accordion-item-title-header'><div class=\"e-n-accordion-item-title-text\"> What type of pumps are Eldex pumps? <\/div><\/span>\n\t\t\t\t\t\t\t<span class='e-n-accordion-item-title-icon'>\n\t\t\t<span class='e-opened' ><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-minus\" viewbox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h384c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t\t<span class='e-closed'><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-plus\" viewbox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H272V64c0-17.67-14.33-32-32-32h-32c-17.67 0-32 14.33-32 32v144H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h144v144c0 17.67 14.33 32 32 32h32c17.67 0 32-14.33 32-32V304h144c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-2125\" class=\"elementor-element elementor-element-0efdeeb e-con-full e-flex e-con e-child\" data-id=\"0efdeeb\" data-element_type=\"container\">\n\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-2125\" class=\"elementor-element elementor-element-a367ea6 e-flex e-con-boxed e-con e-child\" data-id=\"a367ea6\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-5abb19e elementor-widget elementor-widget-text-editor\" data-id=\"5abb19e\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Eldex Optos and HP Series pumps are reciprocating piston-style pumps, meaning the pump fluid chamber is static.

They typically operate in a reciprocating manner, which can produce a pulsating flow. Pulsation dampers can significantly improve the efficiency and reliability of the pumps.<\/p><ul><li>Smooth Flow: Metering pumps are precision devices designed to deliver a consistent amount of fluid. Without a pulsation damper, the pump\u2019s natural reciprocating action can create pulsations in the flow, leading to inconsistencies in the delivered volume. By dampening these pulsations, the damper ensures that the metering pump provides a more uniform flow.<\/li><li>Enhance Measurement Accuracy: In systems where the fluid being pumped is also being measured or monitored (for attributes like flow rate, concentration, etc.), pulsations can make readings erratic and less accurate. The smoother flow produced by introducing a pulsation damper can lead to more consistent and precise measurements.<\/li><li>Improved Discharge Pressure Control: Pulsation dampers can help stabilize discharge pressure, particularly in systems with variations in downstream resistance. A more stable discharge pressure can enhance the pump\u2019s dosing accuracy.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t<details id=\"e-n-accordion-item-9654\" class=\"e-n-accordion-item\" >\n\t\t\t\t<summary class=\"e-n-accordion-item-title\" data-accordion-index=\"5\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-9654\" >\n\t\t\t\t\t<span class='e-n-accordion-item-title-header'><div class=\"e-n-accordion-item-title-text\"> Are 1\/8\" Swagelok fittings standard or optional? <\/div><\/span>\n\t\t\t\t\t\t\t<span class='e-n-accordion-item-title-icon'>\n\t\t\t<span class='e-opened' ><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-minus\" viewbox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h384c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t\t<span class='e-closed'><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-plus\" viewbox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H272V64c0-17.67-14.33-32-32-32h-32c-17.67 0-32 14.33-32 32v144H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h144v144c0 17.67 14.33 32 32 32h32c17.67 0 32-14.33 32-32V304h144c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-9654\" class=\"elementor-element elementor-element-bd20fbb e-con-full e-flex e-con e-child\" data-id=\"bd20fbb\" data-element_type=\"container\">\n\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-9654\" class=\"elementor-element elementor-element-74e94ed e-flex e-con-boxed e-con e-child\" data-id=\"74e94ed\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-11ccd3b elementor-widget elementor-widget-text-editor\" data-id=\"11ccd3b\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Eldex Optos S and M model pumps with pulse dampers come standard with a 10-32 outlet valve.

Always keep your pump and work areas clean, mainly when replacing parts or performing pump maintenance. Small particulates such as dust or grime can interfere with check valve function and potentially lead to scratching of the piston or liquid end. Disconnect the pump from the power supply and wipe it down with a damp cloth. Clean all parts as needed, followed by a rinse, and clean any fluid at the mechanical end of the pump.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><b><span data-contrast=\"auto\">REPLACE VALVE CARTRIDGES AS NEEDED<\/span><\/b><span data-contrast=\"auto\"><b>\u2014<\/b>Take care to replace valve cartridges in a clean area to prevent dust and dirt from entering the pump. Remove the valve from the cylinder and press out the internal components of the valve assembly. Do not allow valve parts to fall out of the valve onto a hard surface. Reassemble the valve following the manufacturer\u2019s instructions and reinstall the valve housing into the liquid end assembly, tightening by hand until just finger-tight. Then, use a wrench and tighten 1\/4 of the turn. Do not exceed 4.5ft\/lb of torque. Be careful not to overtighten, which can cause the sapphire seats to crack. Stabilize the valve with a second wrench when attaching your fittings to prevent further valve tightening.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p><p><b><span data-contrast=\"auto\">UTILIZE PISTON WASH SYSTEM<\/span><\/b><span data-contrast=\"auto\"><b>\u2014<\/b>Piston seal life can often be significantly extended using the piston wash ports integrated into the pump head.

Not all leaks are noticeable, particularly at low flow rates. Place a wick or litmus paper up the drain slots just underneath the liquid ends to test.

Do not reuse the old piston seal, and use the appropriate installation tools supplied by the manufacturer to minimize piston damage. We have found that \u201cbreaking in\u201d the seals with IPA or methanol for an hour or so under conditions similar to your expected operating conditions can enhance seal life, especially with metal-free seals.\u00a0<\/p><p><b><span data-contrast=\"auto\">INSPECT THE SAPPHIRE PISTON\u2014<\/span><\/b><span data-contrast=\"auto\">Check the sapphire for evidence of corrosion or deposits (discoloration or particulates) and clean with a nonabrasive cleaner.
