The HPB motor is the latest innovation in the Staffa range. With increased speed and power ratings compared to our standard HMB motor, it can increase productivity whilst providing the reliability you would expect from a Staffa motor. The new Staffa HPB motor is the perfect fixed displacement motor for industrial applications.
The essential components of series APM212 external gear motors are an aluminium alloy body and two gearwheels supported by plain bearings.
The front flange can be the SAE standard, or the British or German OEM patterns.
Particular attention has been focussed on the design of the shaft seal, which is often affected by back-pressures
The product range of Bucher Hydraulics includes single pumps 05-100-212-212HP-250HP-312HP (corresponding with the common group denominations: 05-1-2-2.5-3) and several combinations of double pumps, triple pumps, and so on, that can be assembled together according to versions of displacement, flanging, and auxiliary valves.
The HMC series variable displacement models have two pre-set displacements which can be chosen
from a wide range to suit specific application requirements. These motors are also available in a
continuously variable version using either hydro-mechanical or electro-hydraulic control methods.
The enhanced variable displacement HPC models include special low friction components, combined with crankcase flushing flow, to achieve increased shaft power. It is used around the world in marine and offshore winch applications and is known for its efficiency and reliability.
The QXM-Mobil internal gear motor was specifically developed for use in mobile applications. Its outstanding efficiency and extremely low noise levels also make a significant contribution to reducing the costs of both energy and anti-noise measures. The QXM design principle, featuring an integral outboard bearing, ensures top-class protection against leakage at the shaft seal.
The QXM-HS (High Speed) internal-gear motor was developed specifically for use at extremely high speeds. Its first-rate efficiency and extremely low noise levels also make a significant contribution to reducing the costs of both energy and anti-noise measures.
Thanks to the special motor flange, adapted for such applications, and the integral ports for auxiliary functions, the motor can be used in many applications without needing any further modification.
