The upgraded PG30 Series gasoline pumps are powered by a 4-cycle, 2-hp Honda engine that offers a low weight to horsepower ratio. Ideal for remote locations where electricity or compressed air are unavailable, the pumps work with single- or double-acting cylinders up to 75 tons at pressures to 10,000 psi. Both models are available with a pop-off style relief valve for use in crimping applications. SPX Hydraulic Technologies. 800-541-1418.
