Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT HS-4 #9055032 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT HS-4 pump is a robust, durable, direct-drive, manometric plunger-type instrument, designed to meet the requirements of variable-speed, high-precision, hydraulic and pneumatic applications. This variable-speed pump is capable of providing constant atm flow rates from 0.1 l/min to 130 l/min with regular duty cycles up to 10 bar. The unique pressure control features of HP HS-4 enable it to be used as a metering, pressurizing, mixer-valve, booster, or fluid-injection device. AGILENT HS-4 is powered by a brushless, DC motor and single-direction drive stroke, providing high efficiency at low speed ranges. The motor has an adjustable speed range of 0-15 rpm, with digital control accuracy of ±0.1 rpm across the RPM range. The digital speed control utilizes a proprietary track-free bearing design which eliminates any sliding friction and reduces wear and noise. The dedicated display gives the user fast visual feedback about the pump's speed, flow, and pressure. KEYSIGHT HS-4 is built with a robust aluminum housing with a generously sized air-output port to maximize delivery performance and minimize heat generation. The Anti-Spiral-Rotation design prevents coiling, which ensures a high-precision and consistent delivery up to the end of the stroke. The high-pressure/temperature resistant check valve installed at the inlet port prevents backflow and allows the pump to return rapidly to initial pressure levels. HS-4 is available in three models according to size, load capacity, and flow properties. The universal motor connection design allows the use of a 12 V, 24 V, or other power source and AC/DC voltage requirements. The optional chipper-type pressure regulator allows for the control of pressure and flow changing. HEWLETT-PACKARD HS-4 provides with safety features, including overpressure, overload, and low-pressure/low-flow protection. AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT HS-4 pump is an ideal choice for variable-speed, high-precision, hydraulic and pneumatic applications. It is suitable for a wide range of applications including laboratory instrumentation, building-up systems, high-pressure pumps, metering and injection applications. This pump offers excellent performance, reliable operation, and cost-effective alternative when compared to traditional pump technologies.
