The 1.5 hp model is the highest‑capacity option in the series, designed for applications that demand very high pressures, significantly higher flow rates, or both. It is well suited for central hydraulic supply, high‑volume testing, flushing, and industrial processes where smaller models reach their performance limits. With a broad range of ratios and configurations, the 1.5 hp pump supports demanding duty cycles while maintaining the flexibility needed for complex systems.
Key Features
- Choice of 10 models, 13 ratios, 50 possible combinations
- Output pressures to 50,000 psi (3448 bar)
- Flows to 22 gpm (83.0 l/min)
- Choice of wetted materials
- Single air head
- Drive pressure 3 to 150 ps (.2 to 10 bar)

Liquids Compatible with Haskel Pumps
To assist in easier pump selection, we have classified various popular liquids in groups and assigned to each group a service code. These service code numbers are featured in the chart to the right and are designated for each pump series. Seals and other wetted materials can be supplied to suit your preferred liquid. For advice, please contact our technical services personnel at 818-843-4000.
Service Codes
1 - Petroleum-based oils, kerosene, ethylene glycol, water with 5% soluble oil.
2 - Plain water, diesel fuel.
3 - Most phosphate ester-based hydraulic e.g. Pydraul, Lindol, Cellulube, Fyrquel, and Houghtosafe 1120 and petroleum-based solvents compatible with UHMWPE (Ultra-high Molecular Weight Polyethylene) dynamic seals and Viton static seals.
4 - Petroleum-based solvents, e.g. aromatic hydrocarbons (benzene, toluene, xylene, hylene, etc.); chlorinated solvents (trichlorethylene, carbon tetrachloride, chlorobenzine, etc.); mercaptans, Dowtherm A, solvents etc.); Dowtherm E, plus all of Group 3 and some mildly corrosive acids compatible with wetted materials. See note 5A for service with methyl-ethyl-ketone, methyl acetone, diacetone, alcohol and freon 22.
5 - Skydrol and Aerosafe hydraulic acetone and some alcohols (ethyl, methyl, and isopropyl). 5A. Also suitable for these if Viton static seals are replaced with EPR; specify number 51331 (no extra charge); e.g., 51331-MDTV-5. Most phosphate ester-based solidify at approximately 30000 psi.
6 - Deionized water; demineralized water.
