pneumatic driven hydraulic pump made in china

PGM-20W is designed with Honda Motor, Manual Valve, High Volumn Oil Tank, Pressure Gauge , Carrying Frame etc. PGM-20W is a Double-acting Horizontal Style Gasoline Powered Hydraulic Pump, can be used in the place where electric power or air source are not available, it"s capable of providing pressurized oil to compatible application: cylinder, crimping tools, cutting tools etc. PGM-20W is designed with Honda Motor, Manual Valve, High Volumn Oil Tank, Pressure Gauge , Carrying Frame etc.

Pistons with O-ring seals operate in, fiberglass wrapped cylinders. The cylinder diameter is constant for a particular pump series. The driving medium pushes the piston down on the compression stroke and lifts it on the suction stroke (the M series has a spring return). No drive air lubricant is required as the piston is pre-lubricated during assembly.

In the hydraulic section, the drive piston connects to the hydraulic plunger/piston. Hydraulic pistons have different sizes depending on their nominal ratio. The higher ratio pumps can achieve higher pressures, but have smaller displacements, which translates to less flow per stroke.

During the down stroke, the inlet check valve keeps the liquid in the pump from flowing back into the suction line while it is compressed by the plunger. On the return or suction stroke, fresh liquid is drawn in through the inlet check valve, while the outlet check valve closes.

These check valves control the flow of liquid through the hydraulic section. They are spring-loaded and have a very low cracking pressure, which allows maximum flow during suction. Inlet check valves are closed by the hydraulic fluid pressure on downstrokes. At the same time, the outlet check valves open when the hydraulic pressure in the pump exceeds the pressure in the system after the pump.

A hydraulic seal is one of the few parts that wear out. Basically, it prevents fluid from flowing into the actuator while the hydraulic piston is moving back and forth. Seal specifications are determined by the fluid, its pressure and temperature. Most Haskel pumps can be operated without contamination by use of a vent or distance piece between the pump section and the air drive.

Ningbo Vicks Hydraulic Co.,Ltd is a holding subsidiary of the listed company Baosi Stock (stock code: 300441), founded in 2007, we"re a national high-tech enterprise with multiple invention patents, own 8 world-leading hydraulic pumps production and inspection lines.
