Allweiler pumps are built to the highest specifications and tolerances for a lifetime of service.

Allweiler Progressing Cavity Pumps

Allweiler Progressing Cavity Pumps are used to pump or meter thin to highly viscous liquids, pasty, neutral or aggressive, pure or abrasive liquids, gaseous liquids or liquids that tend to foam, even liquids with fibrous and solid components.

Shanley Pump and Equipment carries a full line of Allweiler Progressing Cavity Pumps with ranges of 0 GPM to 2500 GPM

The unit is a Self-priming progressing cavity pump, the pumping elements of which are the rotating rotor and the stationary stator. The special shape of these two parts creates sealed chambers, the contents of which are continuously moved in an axial direction from the suction side to the pressure side. Despite rotation of the rotor, no turbulence results; the consistent  chamber volume eliminates crushing forces.

Shanley Pump and Equipment carries a full line of Allweiler Self Cooling Centrifuge Pumps with ranges of 0 GPM to 6400 GPM

All Centrifugal Pumps are rotodynamic pumps which convert Mechanical energy into Hydraulic energy by centripetal force on the liquid. Centrifugal Pumps are used to pump neutral or aggressive liquids, pure or contaminated liquids, cold or hot liquids, toxic, and environmentally hazardous liquids like water, hot water, lubrication oils, emulsions, thermal oils, and chemical products.

Allweiler Three Rotor Screw Pumps

Shanley Pump and Equipment carries a full line of Allweiler Three rotor Screw Pumps with ranges of 0 to 3500 LPM

The Screw pump is one of the oldest and most useful of all pump designs. Three rotor designs utilize one power rotor and two drive rotors which spin inside the casing creating a rolling contact. This contact between the rotors and the fluid being pumped creates a barrier separating the rotors from contact and friction.

This action creates a seal inside the unit that prevents metal to metal contact while efficiently moving the medium being pumped. At Shanley Pump and Equipment, we stock and sell multiple Screw Pumps and accessories for use in any environment and with any fluid.
