Description
Haskel Model 29723-71 0.33HP Air-Driven Liquid Pump
Catalog literature: Liquid Pump Catalog.pdf 
With a nominal pressure ratio of 71:1, the Haskel model 29723-71 0.33HP air-driven liquid pump utilizes a single air head to boost liquid pressures to a maximum of 8800 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
