ADPL & ADBPL Progressive Cavity Metering and Dosing Pumps

Pump Series Description

ADPL Series Icon The ADPL Series of small Progressive Cavity Metering and Dosing Pumps from Liberty Process Equipment offers an ideal solution to many low-flow pumping applications that require high accuracy in volume control at an affordable price. For liquids that are low-viscosity to high-viscosity and abrasive liquids it provides a pumping solution that is much more reliable than other types of metering pumps available on the market today.

Small piston-type metering pumps with check valves have inherent problems of pulsation, sticking and ball check valves sticking and failing. The Liberty ADPL Series solves all of these problems with pulsation free flow, no check valves required and able to handle viscosities up to 20,000 CP. In addition, with its high-accuracy and repeatability it offers a cost-effective alternative to higher-priced "accurate" metering pumps.

The ADBPL pump series offers all the benefits in an accurate metering pump as the ADPL, but in a close-coupled design. This enables you to have a more compact pump package where space is at a premium. It also eliminates the need for a baseplate, coupling, coupling alignment, and coupling guard. Available in 3 sizes, all ADBPL pumps come in three stage designs to handle discharge pressures up to 175 PSI.

All ADBPL and ADPL pumps are available in cast iron and more popular 316 Stainless Steel materials of all wetted parts and are ready to ship same-day from our facility. A wide variety of motors and controls are available for the ADBPL from Liberty Process Equipment to meet your exact control needs and budget.

Liberty Process can offer a drive and control option to meet your needs and budget. From a single fixed spaced rotor in AC or DC to a single hand dial to vary the speed to a remote control PLC, Liberty Process Equipment has your low-flow pumping solutions ready to ship same day.
