A10VSO18 28 45 71DFR31R Variable German Rexroth Plunger Pump replacement
Product Description
The working principle of the hydraulic piston pump is to use the reciprocating motion of the piston in the pump chamber to change the volume of the pump chamber to transport liquid. The structure of the piston pump is mainly composed of the pump chamber, plunger, piston rod, flow distribution valve, oil suction valve, oil discharge valve, etc. The structure of the hydraulic piston pump is relatively simple, mainly composed of the pump chamber, plunger, piston rod, flow distribution valve, oil suction valve, oil discharge valve, etc. The piston pump has a compact structure, small size and light weight.

Application of plunger pump
The main role of a plunger pump is to transform mechanical energy from an external source into pressurized energy through a prime mover. It delivers energy to the hydraulic system as pressure or flow. Known for its ability to handle liquids at high pressures, the plunger pump is widely utilized in numerous applications, such as:
Oil exploration and extraction
Catalytic reactions in the petrochemical sector
Liquid chromatography analysis
Supercritical extraction
Separation processes
Atomic energy research
Environmental science
Process equipment
Experimental setups
Micro-delivery of various liquids
Application of plunger pump
The primary function of a plunger pump is to convert mechanical energy input from an external source into pressurized energy via the prime mover. It transmits energy to the hydraulic system in the form of pressure or flow. Due to its capability to transport liquids at high pressures, the plunger pump is extensively used in various applications, including oil exploration and development, catalytic reactions in the petrochemical industry, liquid chromatography analysis, supercritical extraction, separation processes, atomic energy research, environmental science, process equipment, experimental setups, and the micro-delivery of various liquids.
