Construction Dewatering: Rotary lobe pumps are ideal for wellpointing and sock. Wellpointing and sock require that the pump be able to selfprime, often to 20 ft; be able to pump both air and water without cavitation damage; and be able to overcome air leaks because of a high air handling capability and still continue to prime. Rotary lobe pumps are now the dominate pump used for wellpointing and sock in the USA. Our sister company www.hollandpump.com has over 200 wellpoint/sock pumps in its rental fleet. They have put more than 1.5 million hours on these pumps with outstanding results.
Many mining processes require dewatering. Rotary lobe pumps are well suited for feeding dewatering devices because of their ability to pump a measured, near pulseless flow at any pressure within the pump’s PSI range. Additionally, mining applications are often abrasive. Pump wear rate is greatly effected by pump speed. Typically, rotary lobe pumps run at 200-300 rpm in abrasive applications whereas centrifugal pumps are typically run at 1750 rpm. This results in much faster wear for centrifugal pumps. Rotary lobe pumps deal well with soft, compressible solids and fine abrasives. We recommend that hard solids greater than 1/8″ (3 mm) be removed with an in-line grinder, filter, or knock-out tank.
