LobePro’s history really begins in 1978 when Holland Pump Manufacturing (HPM) started manufacturing pumps in Florida. In 2005, HPM opened a large new plant in Georgia. The rotary lobe pumps manufactured by Holland Pump Manufacturing of Ga. were sold under the LobePro tradename. As LobePro continued to grow Holland Pump Manufacturing of Ga. formed a separate subsidiary, LobePro Inc., so that its management could be solely focused on making the best possible rotary lobe pumps. Holland Pump Manufacturing, Inc.’s key managers operated a fleet of rental pumps that included 250 rotary lobe pumps built by a German manufacturer. During this time, we put over 1.5 million hours on these rotary lobe pumps. Through careful tracking of failures, repairs and maintenance, these key managers realized that many improvements were required and that these improvements could be made without changing the basic design of the pumps. LobePro began by building large frame rotary lobe pumps (SL266 and SL531d) specifically designed for pumping sludge or slurries. Our Large Frame line now includes the following pump sizes: SL133, SL133h, SL266, SL266h, SL399, SL399h and SL531h.
