Aftermarket Replacement V / VQ Single Vane Pumps

Overview of the V and VQ single pumps — balanced, fixed-displacement cartridge pumps on the 20V / 25V / 35V / 45V frames, 7-193 cm³/r. V series runs at 1800 r/min with up to 207 bar on 20V codes 5/8/11 and 172 bar on 25V-45V; VQ series reaches 210 bar and 2700 r/min with lower noise, and 175 bar on 45VQ. All units are new aftermarket replacements, quality checked before shipping.

Selection notes

¹ Pressure is code-specific: on 20V only codes 5/8/11 reach 207 bar (2/14 are 138 bar, 12 is 159 bar); the largest VQ codes are derated too (20VQ 12 to 160 bar, 14 to 140 bar). The trailing items of the model code set ports, mounting and shaft: mounting code omitted = flange with single seal, S = flange with double seal, F = foot mounting; shaft 1 = straight key, 11 = spline, 86 = heavy-duty key (297 spline with the S pilot). Inlet pressure must not exceed 1.4 bar (20 psi) — these pumps are internally drained.

Ordering

The model code must be complete — ring size, mounting, inlet and outlet, shaft and rotation together define the pump. Send the full nameplate code and we will confirm the replacement.
