Model MDSTV-5 Liquid Pump

Description

Haskel Model MDSTV-5 0.33HP Air-Driven Liquid Pump

Catalog literature: Liquid Pump Catalog.pdf

With a nominal pressure ratio of 5:1, the Haskel model MDSTV-5 0.33HP air-driven liquid pump utilizes a single air head to boost liquid pressures to a maximum of 625 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 modifications 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
