Bare Shaft Pumps

Advanced Pressure Systems has enhanced the power end from its Aqua-Dyne affiliate, a proven design already, by upgrading the power frame and cross heads to a much stronger material, ductile iron. Also, now our bare shaft pumps feature a crankshaft machined from billet and are drilled for forced lubrication.

We will offer two models, the APS-S300-15 and the APS-S300-20, capable of handling pressures to 15,000 and 20,000 psi respectively. Both bare shaft pumps feature hinged manifolds for easy access to the quick change valve cartridges, plungers and stuffing boxes.


Features:

  • Rated to 300 HP
  • Flow rates: 48 GPM @ 9,000 psi / 26 GPM @ 15,000 psi / 20 GPM @ 20,000 psi
  • Crankshaft machined from billet, with induction hardened journals
  • Forced lubrication for crankshaft
  • High strength ductile iron power frame
  • Hinged cover to pump well
  • Quick change convertible manifolds from 15,000 to 20,000 psi
  • Hinged trunnion assembly for swing down manifold
  • Quick change cartridge assembly for suction and discharge valves
