ABEL PUMP-Long service time

ABEL PUMP CM – Still pumping even after 30 years

Background

In the state New York, there is a wastewater treatment facility. Some upgrades have made the facility one of the most modern wastewater treatment plants in the area, with a capacity of 658,000 GPD. Today, the facility utilizes the technology and treatment parameters of Active Sludge, by means of Sequencing Batch Reactors (SBR’s).

In 1988, an ABEL model CM piston-diaphragm pump was purchased and installed as an integral component of the sludge dewatering system. The pump takes the underflow from the clarifier and sends the thickened solids to a high pressure (225 psi) plate and frame filter press.

Operation

As pressure begins to build in the filter press, the pump’s CPR valve throttles back on the amount of hydraulic fluid supplied to cylinder between the piston and diaphragm. With less fluid in the cylinder, the stroke length of the diaphragm is reduced, thus decreasing flow. This inherent design of the model CM pump, mechanically reduces the flow as pressure increases without the requirement of Variable Frequency Drive (VFD). In addition, the decrease in hydraulic output results in a drop in the required electrical power required by the motor, thereby saving money.
