SGV

Overview
Description
Specifications

The SGV series is a modular, medium to heavy duty storage filling pump system available in 1, 2, or 3 cylinder configurations to provide a wide range of flows for any storage filling application. It has vacuum jacketed cold ends for minimal cool down losses and economical operation, especially beneficial in liquid hydrogen service. These cold ends are available in a variety of bore sizes so that the pump may be tailored to the flow and pressure requirement of a wide array of applications. The pump is driven by an electric motor through a heavy duty timing belt for maximum longevity. SGV pump skids are available on a retractable base allowing for simple and easy maintenance when connected to rigid vacuum jacketed piping. The drive has a robust self-contained pressurized forced oil lubrication system which is specifically designed to provide maximum drive life in heavy duty applications.

Features & Benefits

  • Modular, compact displacement pumps available in 1, 2, or 3 cylinder configurations provide a wide range of flows
  • Vacuum jacketed cold end for minimal cooldown losses and economical operation, ideal for liquid hydrogen
  • Pressurized oil lubricated drive with integral oil pump and reservoir, allows higher bearing loads/prevent oil leakage
  • Belt driven by electric drive motors allows for extended pump duty
  • Improved cold end assembly design extends seal life
