Pressure on Demand Pneumatic Driven Liquid Pumps

High Pressure Haskel pneumatic driven liquid pumps are designed to provide a safe, reliable and economical, source of hydraulic pressure. This brochure introduces our pneumatic driven liquid pump range. Visit our website at www.haskel.com for more information or to locate a distributor. Why Use Haskel Pneumatic Driven Pumps? Our pumps offer many advantages over electrically driven pumps: • • • • • • • • Safe pneumatic operation – no heat, flame or spark risk Up to 100,000 psi (7000 bar) capability Infinitely variable cycling speed Stall feature at pre-determined pressure to hold that pressure...

Pressure and Flow on Demand This guide will help you to pre-select the pump ideally suited for your application. If you have specific questions, however, we urge you to provide Haskel with the operational details of your application. We will recommend a model and any corresponding accessories. Output Horsepower Ratings The pumps are categorized on their horsepower ratings (see pages 6-7). These are approximate and peak at 100 psi (7 bar), assuming adequate drive, pressure and volume. Peak horsepower is at about 75% nominal ratio x drive pressure, i.e. 100:1 pump @ 100 psi air drive peaks at...

2. Hydraulic Check Valves Anatomy of a Pneumatic Driven Pump 1. Drive Section The piston, complete with “O” ring seal, operates in an epoxy filled, fiberglass wound barrel, the diameter of which is constant throughout a given series of pumps. Drive media forces the piston down on the compression stroke and raises it on the suction stroke (M series have a spring return). The piston is pre-lubricated during assembly and therefore no air line lubricator is necessary. 2. Hydraulic Section/Check Valves The drive piston is linked and connected to the hydraulic plunger/piston in the hydraulic...

1.5 hp (1.12 kW) High Output Flow Pumps Available in a choice of 4 models, these high output, low ratio pumps are capable of pressures to 1200 psi (82 bar) and flow rates of up to 22 gpm (83 l/min). These are “lift” pumps whereby the outlet pressure equals the air drive x the pump ratio plus the inlet pressure. Mounting Brackets All series mounting brackets have 7/16” holes (slots) for 3/8” bolts. Upper mounting brackets are not furnished as standard on single air head non-distance piece units. Dimensional Data Mounting Brackets Model DSTV-1.5 has a maximum air drive of 150 psi (10 bar) and...

Maximum Working Pressure Nominal Ratio Consult chart on page 6 for more information regarding continuous/intermittent pressures. • Flows to 5 gpm (15 l/min) • Choice of wetted materials • Double and triple air heads • Drive pressure 3 to 100 psi (.2 to 7 bar) When using high pressure ratio pumps the reliability of the XH models (-452 through -1373) will be improved with an air driven supercharge pump, not only to simplify priming but to reduce fatigue stresses. The higher the supercharge, the better the results. Also install a relief valve to protect the lower pressure pump from potential...
