Made from high-performance polypropylene, these liquid-transfer pumps (photo, p. 32I-7) will safely deliver most solvents, acids, caustics and oils from 5–55-gal drums at a rate of 4 gal/min, depending on the viscosity. Typically, owners will need to change O-rings once or twice during the pump’s 8–10-year lifetime. The pumps are offered with Viton, Santoprene, EPDM or Nitrile sealing, depending on the fluid. — GoatThroat Pumps, Milford, Conn.
