Rotary Lobe Pumps

Benefits vs. Competitor Dual Vacuum Wellpoint Pumps
Our Rotary Lobe pumps are simple and reliable because the system consists of an engine, a gear reducer, and our LobePro pump end
Our Rotary Lobe pumps self-prime to 25’ with a strong vacuum
Centrifugal pumps are adversely affected by entrained air, inadequate Net Positive Suction Head (NPSH) or by not operating within 10% of their best efficiency point (BEP). In contrast, our pumps will happily pump air and water, have low suction requirements and operation at any points within their operating range is fine
Wellpoint applications typically require a pump to maintain a pumpdown condition whereby the system in primarily pumping air
Competitor wellpoint pumps featuring dual vacuum pumps with airwater separators are prone to both carryover and failure
Other competitors utilize oil flood reciprocating vacuum pumps which are typically capable of 130 CFM for 8” pumps and 270 CFM for 12” pumps. By contrast, our LobePro pump ends are capable of 174 CFM for our W8R 8” pump and 348 CFM for our W12R 12” pump
Benefits vs. Competitor Positive Displacement (PV) Rotary Lobe Pumps
Long lasting, leak free seals...avoid the dreaded pressure bottle
Our seals are simple to install and pressure tested for leaks before shipment
Our seals do not require a pressure bottle containing reserve oil seal oil below 100 psi. Pressure bottles are an unnecessary annoyance requiring daily monitoring.
We do not use packing which is, of course, designed to leak
We use mechanical seals which are designed for extreme shock and vibration
Wear parts shipped within 2 working days of order receipt or the Parts are Free!
This guarantee applies for 5 years after the purchase of our Rotary Lobe pump
Run dry ability - our mechanical seals are oil cooled, permitting limited run-dry operation
Special mechanical seals are oil cooled permitting limited dry running
Steady, Pulseless flow due to helix, 4 wing lobe design
Ease of maintenance
Mechanical seals, lobes, and wear plates can be changed on site without disconnecting suction and discharge fittings.
No clutches are complicated timing gears to worry about.
Simple improvements such as using corrosion resistant bolts, nuts and materials in the wet end which greatly facilitates disassembly
