Description

Haskel Model DSTV-1.5 1.5 HP Air-Driven Liquid Pump

Catalog literature: Liquid Pump Catalog.pdf Acrobat DC

With a nominal pressure ratio of 1.5:1, the Haskel model DSTV-1.5 1.5 HP air-driven liquid pump utilizes a single air head to boost liquid pressures to a maximum of 300 PSIG.

Features & Benefits:

  • Safe pneumatic operation – no heat, flame or spark risk
  • Infinitely variable cycling speed
  • Stall at pre-determined pressure to hold that pressure without consuming power
  • Problem-free stop/start applications
  • Easily automated – many modification and control options
  • Suitable for most liquids and liquefied gases
  • Alternative gas drive options available, such as sour gas, natural gas, boil off gases, or nitrogen
  • Robust, reliable, compact and easy to maintain proven design
  • No need for air line lubrication – saves costs and prevents contamination
  • Unbalanced cycling spool provides immediate response to pressure changes
  • Can be manufactured to ATEX, CE and NACE
