Rugged, dependable performance under high pressure

Every component of the D-Series is specifically designed for maximum efficiency, dependability, durability and reliability in performing continuous operation in heavy duty applications with severe duty cycles and temperature conditions, all within the industry leading package size and power density.

The broad range of shaft drives, integrated valves, and side or rear port options gives great flexibility in system design. Coupled with the modularity and compact nature of the D-series of pumps, a wide array of applications rely on the D-pumps.

20% smaller than conventional gear products, our cast iron gear pumps give great power density in a small package.

Features and benefits

Thrust plate design for high efficiency over a wide temperature range

Teflon® coated bushings for extended life under extreme temperature and pressure conditions

High strength cast iron construction for efficient performance in continuous operation

Easy installation in optimized machines due to compact, power-dense design

Viton® seals are standard to sustain higher temperature and fluid capabilities
