Vane pumps type PVL

variable displacement

PVL are variable displacement vane pumps equipped with mechanical compensator ® for outlet pressure and max displacement adjustment ®, ®. These low-noise pumps are available in 3 different size, have flange ports according to ISO 3019/2 and are designed to operate with anti-wear oil according to DIN 51524...535 and fire-resistant fluids with same lubricating characteristics.

Wide variety of displacements: from 6,8

up to 43 cm3/rev.

Max pressure up to 150 bar.

PVL-4

@® rotor with vanes

@® stroke limiter piston and screw for max displacement adjustment

@ (jg) spring and screw for pressure compensator adjustment
