Hydromot Hydraulic Motors – Frequently Asked Questions
What are the main features of the CPMM hydraulic motors?
The CPMM hydraulic motors are characterized by a spool valve with gerotor and are optimized for compact spaces. They feature an internal check valve and can be used without a case drain line. The motors are available with or without flange and offer side or end ports. Displacement volumes range from 8.2 cm³/rev to 50.3 cm³/rev, and various shaft types (cylindrical or splined) and thread connections (BSPP or SAE) are available. The direction of rotation can be configured.
What designs and seals are available in the CPM and CPHM hydraulic motors?
The CPM and CPHM hydraulic motors both feature a spool valve with gerotor and a compact design optimized for tight spaces. They include an internal check valve and can be used without a case drain. A high-pressure shaft seal up to 150 bar is standard. The CPHM series also offers various special versions. Both series offer a wide range of mounting flanges (oval flange, magneto flange, square flange, wheel flange) and shaft variants.
How do CPMJ hydraulic motors differ from other models?
The CPMJ hydraulic motors are specially designed as wheel motors. They feature a spool valve with gerotor and are characterized by low starting torque and high efficiency. Like other models, they are optimized for tight spaces, include an internal check valve, and can operate without a case drain. A high-pressure shaft seal up to 150 bar is standard. They are available in displacements from 66.8 cm³/rev to 370.0 cm³/rev and with various shaft types including cylindrical and tapered.
What makes the CPRM hydraulic motor unique?
The CPRM hydraulic motor features a spool valve with geroller, which sets it apart from the gerotor models. It has a compact design, ideal for confined spaces, and includes an internal check valve. Operation without a case drain is possible, and a high-pressure shaft seal up to 150 bar is standard. The CPRM series offers displacements from 36.0 cm³/rev to 381.4 cm³/rev and a wide variety of mounting flanges and shaft types.
What are the key features of the CPMS hydraulic motors and their advantages in radial load?
CPMS hydraulic motors are disc valve types with geroller and offer low starting torque, high efficiency, and high pressure resistance. They include an internal check valve and can be operated without a case drain. A key feature is the taper roller bearing, which is designed for high radial loads. This allows the motors to handle high axial and radial forces. Displacements range from 80.6 cm³/rev to 475.0 cm³/rev.
