How peristaltic and diaphragm metering pumps compare on pressure, solids tolerance, sealing, maintenance, and cost, and which to choose for chemical dosing.

Why peristaltic pumps self-prime but have a lift limit, how the suction tube collapses under vacuum, and how to size the suction line for reliable priming.

Which peristaltic pump spares a process plant should stock — tubes, rollers, barbs, fuses — in what quantity, and how to organize the cabinet.

How peristaltic pumps dose biocide, scale inhibitor, and pH adjuster on cooling towers, and how to choose tube material and sizing.

How duty cycle heats a peristaltic pump, why intermittent-sized pumps overheat on 24/7 duty, and how to derate speed and size the head for continuous running.

How peristaltic and centrifugal pumps compare on flow, pressure, sealing, viscosity, abrasion, cost, and maintenance, and which to choose.

Why peristaltic pump flow changes after a tube change, and how to re-seat the tube, re-set occlusion, and re-calibrate the run time.

How peristaltic pumps handle abrasive slurries, why tubing wears, and how to size bore, speed, occlusion, and material for long slurry duty.

How plastic and stainless peristaltic pump heads differ in wash-down, corrosion, weight, and cost, and which to choose for your installation.

How peristaltic pumps dose detergent, rinse aid, and fabric softener in appliances and dispensers, including viscous fluids, foam, and repeatability.
