Product	Orbit Hydraulic Motor
Model No.	BMV-400-4-T-D
Displacement	400 Cc
Brand	XLF Hydraulic
Highlight	BSP Port Hydraulic Orbital Motor, 400cc Hydraulic Orbital Motor, 4-bolt Hydraulic Orbital Motor

The BMV-400-4-T-D is a gerotor hydraulic motor with a displacement of 400cc/rev, belonging to the large-displacement and high-pressure models in the BMV series. This model features a 4-Bolt Square Flange mounting method, is equipped with a 1:10 Tapered Shaft and BSP standard oil ports, and is a high-performance drive solution specially designed for heavy-duty industrial applications.

As a direct replacement for the Eaton Char-Lynn 10000 series, Danfoss OMV series, and M+S MV series, this motor adopts an advanced Geroler gear set design and a disc-type valve distribution structure, providing excellent starting torque and stable low-speed performance within a compact volume. The 400cc displacement achieves a good balance between torque output and speed range, and can be widely used in various heavy-duty occasions such as construction machinery, agricultural equipment, and industrial transmission.

High-Pressure Performance (Core Strength of BMV Series)

BMV series orbital motors feature outstanding high-pressure capability:

Continuous working pressure: 200 bar (25% higher than standard models)

Peak pressure: 280 bar for extreme overloads

Starting torque: over 92% of theoretical torque

1:10 Tapered Shaft – Reliable & Backlash-Free

Backlash-free transmission via radial clamping force

Simple installation and disassembly with a single shaft-end nut

High torque capacity with large tapered contact area

Self-locking design prevents loosening in operation

Geroler Gear Set – Rolling Friction Design

Rollers reduce friction, improving mechanical efficiency by 5–8% vs traditional gerotors

Optimized flow paths deliver low starting pressure

B10 service life: ≥10,000 hours at rated conditions
