With displacements from 0.19 to 200.3 cc/rev and maximum continuous working pressures of up to 280 bar this range of gear pumps satisfies demands of a wide range of applications.

The combination of FEM (finite element method) simulation and modern production techniques has seen one range of hydraulic systems satisfy demands for efficiency, reliability and reduced noise.

The range of positive displacement, hydraulic gear pumps is available in single or multiple pump format and can be supplied with integral relief valve on request.

Not just huge stocks of gear pumps available for next day delivery but the technical expertise to specify for complex and simple applications alike . . . you name the application, we specify the pump.
