Haskel Model MS-188 0.33HP Air Driven Liquid Pump with Maximum Cycles of 325/min

With a nominal pressure ratio of 188:1, the Haskel model MS-188 0.33HP air-driven liquid pump utilizes a single air head to boost liquid pressures to a maximum of 15000 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 airline lubrication saves costs and prevents contamination
Unbalanced cycling spool provides immediate response to pressure changes
Can be manufactured to ATEX, CE and NACE
