I work in the pump sector and write about water and wastewater pumping, including double-suction, sludge, and submersible sewage pumps. My contributions to BBP focus on making pump types, sizing considerations, installation needs, and common operating problems easier for buyers and equipment users to understand.
Double Suction Pump Guide for Engineers and Buyers
A Double Suction Pump is a centrifugal pump design where flow is supplied to both sides of the impeller rather than fed into one side only. For the engineer and buyer it is not merely the question “what is it?”.…
Sludge Pump Guide: Types, Selection, Solids, and Failure Modes
A sludge pump handles semi-liquid sludge with suspended solids, viscosity, grit, fibers, or settled debris. Naming the pump is simple; choosing the right pump for the material is what prevents lost flow, burned motors, and plugged discharge lines. Quick Specs:…
Submersible Sewage Pump: How Engineers Select, Size, Install, and Maintain Them
A submersible sewage pump is an unusual animal: it is a setback – taking gravity out of the equation, it lifts raw waste, solids, TP and all, from below-grate to the drain line above. Choosing well and it will be…
The Engineer’s Field Guide to End Suction Pumps: Types, Selection & Long-Term Performance
Quick Specs: End Suction Centrifugal Pump Pump Classification Single-stage end suction centrifugal pump Working Principle Centrifugal force via rotating impeller converts motor energy to fluid velocity and pressure Typical Flow Range 5–5,000 GPM (1–1,200 m³/h) Typical Head Range 15–650 ft…
Sewage Grinder Pump: The Engineer’s Field Guide to Cutters, Codes, and 25-Year Service Life
A sewage grinder pump shreds wipes, fibrous solids, and toilet paper into a fine slurry before the impeller ever sees them — which is exactly why properties on low-pressure sewer networks, basement bathrooms below the main, and commercial lift stations…
Gravel Pump: The Engineering Guide for Mining and Dredging Operations
A gravel pump is a high-capacity (200 m³/hr+ / 900 US gpm+) centrifugal pump designed with large passageways and an open or recessed impeller so it can move coarse abrasive solids—sand, gravel, rocks and slurry—without blocking up or wearing out…
The Submersible Dredge Pump Engineering Guide: From Pump Curves to Total Cost of Ownership
A submersible dredge pump is a centrifugal slurry-handling machine that operates fully submerged in the material being moved, eliminating the suction-lift problem that caps surface-mounted alternatives at roughly eight meters of depth. This guide walks through the engineering theory, vendor-neutral…
Horizontal Slurry Pumps: The Engineering Guide to Selection, Wear Life, and Total Cost of Ownership
A horizontal slurry pump is a centrifugal pump made using heavily-walled casings and wear tolerant wet ends such that it can pass industrial slurry full of abrasive solids without self-destructing in a matter of weeks. Such pumps are designed are…
