Hydraulic Drive Option for Sliding Vane Pumps

Hydraulic Drive Option Overview

When an electric motor drive is not a preferred option, misalignment has been an issue, or you have limited space, the hydraulic drive is a great solution. This option allows for direct mounting of a hydraulic motor and forms a compact alignment. The hydraulic drive option is available with the PT-, PZ- and Z-Series pumps. The hydraulic drive configuration is designated by the lettter "H" within the model number. The model numbers for our hydraulic drive sliding vane pumps begin with PTH, PZH and ZH. The operating specifications for the hydraulic models are the same as the standard PT-, PZ- and Z-models. For details on the operating specifications, refer to the pages containing our standard models.



  • Available with foot mount designs (PT-, PZ-, and Z-Series pumps only). The hydraulic versions are designated by PTH, PZH, and ZH.
  • Compatible with the Z-model truck mount designs (ZH200, ZH3200 & ZH4200)
  • Six vanes/blades design with vane drivers
  • Mechanically sealed pump with a wide variety of sealing options
  • Depending on the model, available with NPT or ANSI flanges
  • Pump casing and heads: Gray iron or ductile iron.
  • Cam and sideplates: Gray iron
  • Rotor and flanges: Ductile iron
  • Seal seat: Silicon carbide (exception: PT-Series uses cast iron only)
  • O-rings: Buna-N, PTFE, Viton®, Neoprene®. Registered trademarks of DuPont.
  • Blades: Advanced polymers
  • Eliminates the need for an electric motor
  • Self-adjusting sliding vanes maximizes performance
  • Cam and sideplates can be replaced. Sideplates are reversible
  • Maintenance is simple and cost effective: By simply removing the pump head, you can easily replace the internals without disturbing the piping
  • Can handle small amounts of vapor
  • Excellent suction lift is great for clearing suction and discharge lines
