These explosion-proof pumps feature cool fin design technology, which effectively disperses heat, keeping pumps cooler and leading to longer service life. From 1/2 to 7 1/2 hp, the company offers a broad line of explosion-proof pumps. Automatic models, with integral control design, are available to eliminate the need for expensive control panels. Oil filled motors and cast iron construction allow these pumps to function even when not submerged in liquid. Explosion-proof package systems are also available in a variety of discharge sizes and configurations. All pumps are FM, UL, CSA or NEMA 7 automatic submersible units. Every explosion-proof pump is 100% pressure tested under water.
