Dewatered Sludge Transfer

Thick sludge from centrifuges or filter presses calls for a review of suction feeding, starting torque, and abrasive wear. Low-speed lobe transfer is an option to review when inlet filling and wet-end maintenance access matter.

Explore Dewatered Sludge Transfer

Dry solids content, sludge consistency, and startup conditions.
Grit content and its effect on rotor and liner selection.
Suction feed arrangement and access for wet-end service.

MBR Membrane Suction & Backwash

Membrane bioreactor systems use suction to draw filtrate and periodic backwash to clean the membrane. Using one lobe pump for both directions requires a coordinated piping, valve, relief, and control design.

Explore MBR Suction & Backwash

Required suction vacuum and flow in each direction.
Backwash pressure, cycle timing, and reversal controls.
Priming conditions, air exposure, and seal cooling.

Raw Sewage & Gritty Dirty Water

Raw sewage, primary sediment, and storm runoff can contain sand, grit, leaves, and rags. Review the solids and fiber load before selecting rotor clearances, wear protection, and any upstream screening.

Explore Raw Sewage & Dirty Water

Particle size, grit concentration, and abrasive material.
Rags and long fibers that may need screening or maceration.
Suction layout, flow variation, and liner service access.

What to Share for Pump Selection

Selection depends on the actual fluid, duty point, and installation. Share available measurements, photos, or a piping sketch for review.

Fluid: sludge or wastewater type, dry solids content, temperature, and grit or fiber evidence.
Duty: required flow, discharge pressure, operating hours, and any suction/backwash cycle.
Installation: suction lift, pipe lengths and sizes, power supply, and maintenance space.
