Balcrank 5:1 Panther Carbon Steel Stub Pump is for the distribution of oil products up to 700' or for the simultaneous service (low to medium usage) on up to 2 reels. The pump is bare, with no connecting hoses, and features built-in pressure relief, a double-acting, true pump ratio and balanced flow displacement, as well as enlarged flow passages and high-performance check valves. This unit, designed for oil and light fluids, includes a heavy duty air motor with a thick wall housing and long stroke design, though the unit still offers a quiet operation, and the positive trip air valve prevents stalling. This Panther HP Pump offers a 5:1 pressure ratio, 3.25 stroke, free flow of 5.4 gpm, and operating air pressure range of 10-150 PSI, and this unit comes with a five (5) year warranty.
