Aftermarket Replacement MV037 Vane Motors

MV037 Vane Motors

The MV037 is a high-torque vane motor — maximum torque at start-up and stall, a nearly flat torque curve, and no non-ferrous metals inside. Built from hardened materials, the motor is unaffected by the cavitation that typically occurs in dynamic braking and overrunning-load circuits. Single-rotor displacements run from 197 to 606 cm³/r (12 to 37 in³); two-port double-stack versions cover 1049 to 1213 cm³/r (64 to 74 in³) and four-port units 393 to 1213 cm³/r (24 to 74 in³). Pressure designs are Code 61 (A2 / A4 / C2) and Code 62 (D2 / D4 · 310 bar · 4,500 psi), with speeds up to 1000 rpm, maximum torque of 1,783 N·m on Code 61 and 5,390 N·m on Code 62, and up to 336 kW (450 HP). Mounting is SAE D. All units are new aftermarket replacements, quality checked before shipping; send us the complete ordering code and we confirm the fit before ordering.

Selection notes

The MV037 uses a ten-item ordering code: series - porting - rotating group - displacement - shaft - bearing - shaft seal - body O-ring - case O-ring - special index. Single-rotor displacement codes are 012 / 016 / 020 / 026 / 032 / 037 (197-606 cm³/r); two-port double-stack 064 / 069 / 074 (rotating groups 32/32, 32/37, 37/37); four-port 024-074 (series/parallel circuits, with 036 / 046 / 058 / 069 needing a logic circuit for 2-speed / 3-speed operation). Code 62 (310 bar · 4,500 psi) is available on MV037 and MV057 only - the MV015 has no high-pressure version. Items that are not required are omitted, as the official ordering footer allows.

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.
