Haskel Model 8HSFD-225 – 8HP Air-Driven Liquid Pump

Haskel Model 8HSFD-225 – 8HP Air-Driven Liquid Pump

High-Pressure, High-Performance Pumping for Demanding Liquid Applications

The Haskel Model 8HSFD-225 is an 8 HP air-driven liquid pump engineered for ultra-high-pressure applications requiring exceptional reliability and stable performance. With a nominal pressure ratio of 225:1, this pump is designed to boost liquid pressure up to 25,000 PSIG, delivering consistent power through a compact and robust single-air-head design.

Features & Benefits

• Safe pneumatic operation – eliminates risks from heat, sparks, or flames.

• Infinitely variable cycling speed for precise flow and pressure control.

• Automatic stall at pre-set pressure, holding pressure without consuming power.

• Reliable stop/start performance ideal for intermittent or repetitive duty cycles.

• Easy automation with multiple configuration and control options.

• Compatible with most liquids and liquefied gases.

• Alternative gas drive options available (sour gas, natural gas, boil-off gas, nitrogen).

• Low-maintenance design with no need for air-line lubrication—reduces cost and prevents contamination.

• Fast pressure-change response thanks to the unbalanced cycling spool.

• Can be manufactured to comply with ATEX, CE, and NACE requirements.

• Proven Haskel durability—compact, rugged, and dependable in harsh conditions.
