Key Benefits

What This Unit Does Well

Displacement range from 50 to 395 cc/r allows matching to various hydraulic circuit demands
Rated pressure up to 13.8 MPa supports consistent performance in demanding industrial environments
Spool valving and gerotor sealing reduce internal leakage and improve long-term reliability
Multiple mounting flanges, shafts and ports simplify integration into existing machinery
Compact design reduces space requirements in tight engine compartments
Direction and speed control are smooth and precise, suitable for repetitive cycle operations

Application Scenarios

Where It Is Used

Excavator swing and boom control where consistent torque and responsive speed are required
Wheel loader bucket lift and tilt functions under variable load conditions
Lift truck mast operation with stable speed and minimal pressure drop
Fishing winch systems needing controlled reverse rotation and high starting torque
Plastic injection machines requiring precise, repeatable hydraulic motion

Fit

Who It Is For

Machinery repair shops sourcing replacement motors for excavators and loaders
Contractors maintaining fleets of construction equipment with limited spare parts availability
Parts distributors stocking hydraulic motors for regional distribution in Africa and Southeast Asia
Engineering teams integrating hydraulic motors into custom-built machinery or retrofit projects

Buyer Pain

Problems It Solves

Mismatched motor displacement causing poor system response or excessive energy use
Frequent seal failure due to low-pressure shaft seals in high-load applications
Lack of mounting compatibility forcing custom brackets or redesigns
Unpredictable speed control in variable load scenarios due to poor motor design
Long lead times for OEM motors when original equipment is discontinued

Gerotor-type internal sealing mechanism with high-pressure resistance
Spool valve assembly for precise flow and pressure control
Rubber or metal gasket seals at flange joints for leak prevention

Process

How an Order Is Handled

You provide the machine model, hydraulic circuit pressure, flow rate and mounting requirements
We match the BzzSeries 2K motor with the correct displacement, porting and flange
You confirm the specification sheet and receive a sample or photo before ordering
We prepare the motor, test run it under rated pressure and record the output
Unit is packed in carton, palletized with plastic wrap, and shipped within 3-7 days after payment

Quality Control

Checks Before Loading

Each motor is tested under rated pressure and speed before packing
Shaft seal and spool valve function are verified during test run
External finish, flange alignment and port threading are inspected visually
Random samples are tested for torque output and leakage at the warehouse

Customisation

What Can Be Changed

Custom displacement within the 50-395 cc/r range to match specific hydraulic demand
Custom shaft length, diameter or keyway for direct integration
Custom port size, location or thread type to match existing manifold
Custom flange type or mounting bolt pattern for specific machine design
Special paint or coating for corrosion resistance in harsh environments

Honest Comparison

How It Compares With the Alternatives

Standard gear motor	Orbital design offers higher efficiency and smoother torque delivery at low speeds
Fixed displacement vane motor	Orbital motor handles higher pressure and has longer seal life under continuous duty
Piston motor	Lower cost and simpler maintenance, but less precise speed control under variable load

Use Guide

Using It Well

Install with proper alignment to prevent shaft misload and seal damage
Use only clean hydraulic fluid with viscosity matching the motor's operating range
Check for leaks at ports and seals after initial operation and after 50 hours
Replace seals during maintenance if pressure drop or speed loss is detected
Avoid sudden pressure spikes during start-up to prevent internal component stress
