Radial Piston Pump

The Moog Radial Piston Pump, also known as RKP, has served the industrial market for over four decades and is widely known for its robust and reliable design. 

The turbine features low flow/pressure pulsation and a low noise emission.

It offers greater durability and quieter performance not only when compared to the older version, but also when compared to the state-of-art designs in the marketplace. 

Overview

The Moog Radial Piston pump comes in 7 pump sizes between 19 cc and 250 cc per revolution (19, 32, 45, 63, 80, 140 and 250) and has a maximum speed range of 1,800 to 2,900 rpm, depending on pump size.

  • The standard design permits continuous pressure to 280 bar (4,000 psi) with 350 bar (5,000 psi) peak limit and the high-pressure version is capable of continuous pressures up to 350 bar (5,000 psi) with 420 bar (6,000 psi) peak limit
  • Various mounting flanges and housings conforming to latest SAE and ISO standards
  • Clockwise and counter-clockwise direction of shaft rotation
  • Accessories available to limit maximum flow
