The 1500 - 2900 K/M Series Pump/Motor utilizes the many design and application features of the widely accepted HYDRECO gear pump and motor technology.
See individual size pages for model and size details.
 

The 1500K/M Series Pump/Motor utilizes the many design and application features of the widely accepted HYDRECO gear pump and motor technology. The pump contains pressure-balanced wear plates. The series maintains its bi-rotational pump or motor capabilities made possible by use of check valves which drain back to the low pressure side. The 1500M has a mechanical face seal which allows back pressures up to 2000 psi with no case drain. The cipr range is .74 – 2.07 with an operating pressure of 2500 psi.

Rated to 3000 PSI and 3000 RPM (motors to 3600 RPM) the 1900 series pumps & motors utilize a very rigid, doweled, two piece construction. The pump contains pressure-balanced wear plates. The design results in especially high overall efficiency. The cipr range is 2.53 – 6.70.

The 2000M Series is a bi-rotational Pump/Motor. Operating as pumps, the smaller units can be applied at speeds up to 2400 rpm and pressure up to 1500 psi. Operating as motors, the same pressure can be used, but the speed ratings are further increased. The most important feature is its mechanical face seal. This allows for back pressure up to 1500 psi with no case drain. The cipr is 2.08 – 5.20.

Rated to 3000 PSI and 3000 RPM the 2200 size pumps utilize a very rigid, doweled, two piece construction. The pump contains pressure-balanced wear plates. The design results in especially high overall efficiency. Rotation may be changed in the field with no new or additional parts. The cipr is 4.31 – 6.21.
 

Rated to 3000 PSI and 2750 RPM. Operating as motors, the same pressure can be used, but the speed ratings are further increased. Pump exhibits high horsepower – weight ratios. May be used as uni-rotation motors. Cipr is 6.50 – 9.76.
 

Rated to 3000 PSI and 2500 RPM. The pump contains pressure-balanced wear plates. The design results in especially high overall efficiency. Rotation may be changed in the field with no new or additional parts. The cipr is 8.33 – 14.33
