The 3 hp model is intended for continuous or high‑duty extreme‑pressure applications where both pressure and air drive power must be sustained over longer cycles. It uses the same proven high‑pressure architecture as the 2 and 2.2 hp models, but is optimized for applications that demand greater drive energy and operational margin.

- Output pressures to 33000 psi (2275 bar)
- Flow rates to 8 gpm (30 l/min)
- Single air head

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.
