A4VSO piston pump Rexroth A4VSO pump

Features

– Chemical Froth Hydraulic Axial Piston Polyurethane Metering Pump
– High metering accuracy and reproducibility of the variable pumped volumes
– Robust manual adjustment via hand wheel with integral precision measuring scale
– Operating pressure up to 250 bar
– Low pulsation of the pumped medium
– Pump components are compatible with the pumped media (polyol, isocyanate) due to special pairings of materials and sealing elements
– Low-noise
– Excellent volumetric efficiency for high metering accuracy
– Double shaft seals with buffer fluid ports to guarantee safe operation (and protect the environment)
– With corrosion protection

Installation position  
The pump must be completely filled with fluid. If installed with the shaft pointing upwards, the top leakage fluid port must be connected to the housing for both types of circuit to ensure that the housing is vented in the vicinity of the bearing.
Preferred installation position: drive shaft horizontal. The adjustment display in the hand wheel can only be guaranteed to work if the adjusting spindle is installed -30° to +30° from the horizontal.
Fluid 
The pump and meter fluids for manufacturing polyurethane.  
Leakage fluid   
Max. Leakage fluid pressure PL max. 10 bars. In the closed circuit, pump ports A and B are separated from the housing space.
The leakage fluid must be removed via port T1 or T2 using a separate line. In the open circuit, the suction port S is connected to the housing space. There is no need for a line for the leakage fluid. Ports T1 and T2 are plugged. The filling pressure at port S acts on the shaft sealing ring via the housing space. The service life of the shaft sealing ring decreases as the pressure of the leakage fluid or the filling pressure at port S increases.
Operating temperature range  
Optimum operating temperature range 10-50°C. Maximum operating temperature tmax.80°C
The permitted working temperature depends on the lubricity of the fluid. The maximum fluid temperature must not be exceeded even locally (e.g. no more than 5K over the leakage fluid temperature).  
Control unit MA – Manual adjustment 
Turning the hand wheel turns a self-locking threaded spindle which steplessly adjusts the pump’s swivel section, and thus the volumetric flow in the range from Vg 0 to Vg max.
