Blackmer Model LGB1 Motor Speed Pump

This 1-inch motor speed pump has long been popular for cylinder filling, small volume motor fueling and supplying small vaporizers. It offers the same heavy-duty construction of larger Blackmer models and is available in two mounting styles and capacity ranges. The LGB1 model is equipped with a coupling and bracket for mounting to a conventional base. The LGB1 model will handle up to 10 U.S. gpm (38 lpm). The LGB1P model offers 50% greater capacity and will handle up to 15 U.S. gpm (57 lpm).

This model has a 1-inch NPT tapped ports and use an exclusive "combination" valve that acts as both a back-to-tank bypass valve and as an internal safety relief valve. This feature lowers installation costs by eliminating the need for a separate bypass valve. It also assures pressure relief if the back-to-tank bypass line is closed..

Standard construction materials for this model includes Buna-N mechanical seals and Duravanes for handling both LP-gas and anhydrous ammonia. Optional viton fitted mechanical seals and laminate vanes are also available. Maximum differential pressure is 126 psi (862 kPa) for both models.
