RB series hydraulic diaphragm metering pump

RB series hydraulic diaphragm metering pumpIt is a hydraulic driven diaphragm positive displacement pump that operates reliably. After readjustment and improvement, the extended pump can better meet the work requirements of users. The flow rate of the pump can be adjusted whether it is working or stopped. Under constant pressure, temperature, and pump flow regulation settings, the repeated metering accuracy of the discharged liquid is within ± 1% of the rated flow range. The RB series pump is a reliable, compact, and flow controllable diaphragm metering pump. Its plunger moves back and forth with a certain stroke, pushing a certain volume of hydraulic oil. The hydraulic oil pushes the process material through the PTFE diaphragm, thus producing the conveying process of the pump. Double ball check valves are installed at the inlet and outlet of the pump to ensure constant metering accuracy. The flow rate of the pump is regulated by adjusting the hydraulic bypass flow rate. The repeatability of measurement can only be achieved when the volume of hydraulic oil in the piston chamber remains constant for each stroke. By briefly connecting the piston chamber and oil tank at the end of each suction stroke and the beginning of each discharge stroke, timely replenishment of lost oil is achieved.

Advantages and characteristics of RB series hydraulic diaphragm metering pumpHydraulic balanced diaphragm design, with a lifespan of up to 96000 hours, eliminating the need for dynamic sealing and maintaining plunger packing. The exhaust system configured on the hydraulic end of the pump makes it more convenient to start a new pump and start after maintenance. By configuring an oil bath lubricated worm gear transmission method, the pump drive part runs smoothly and without impact, and the pump worm gear and bearings have a longer service lifeThe sealed dust-proof cast iron box design ensures the reliable and safe operation of the pump in hazardous areas and environmental conditions. The thousand level flow regulating mechanism ensures the pump has high-precision flow output capability. For overpressure conditions, the pump has a built-in pressure relief valve to ensure automatic protection of the hydraulic circuit system. The flexible configuration of high-performance containerized one-way valves ensures consistent reliability and sealing capability in each stroke. Different metal and non-metal material hydraulic end options are provided for various chemical corrosion resistance requirements. For low flow or high temperature usage needs, the pump has a wide range of flow adaptability and environmental temperature adaptability. Single head and double head are optional.
