Peristaltic/Hose Pumps
Peristaltic (hose) pumps move fluid by squeezing a flexible hose or tube with rollers or shoes. The fluid only touches the inside of the hose, so these pumps handle abrasive slurries, corrosive chemicals and shear-sensitive products without seals or valves to wear out.
Advantages
- Seal-less design – no leaks and no seals to replace
- Handles abrasives and solids – slurries, lime, sludge and mining fluids
- Gentle pumping – protects shear-sensitive products
- Self-priming and dry-run capable – tolerant of upsets
- Accurate metering – flow proportional to speed
Selection Tips
Pump size depends on flow, pressure and duty. Running slower extends hose life. Choose hose material (natural rubber, Buna, EPDM, Hypalon) for chemical compatibility. Keep spare hoses on hand, since the hose is the main wear item.
Centro supplies peristaltic hose pumps and replacement hoses for chemical feed and slurry transfer.

FAQS
- Flow (GPM) + total dynamic head (TDH), fluid details (chemistry, temp, solids/viscosity), suction conditions (NPSHa), desired materials, seal type, driver/voltage, connection sizes, and duty cycle.
- The total head the pump must overcome: static lift + discharge head + pressure requirements + friction losses in pipe/fittings/valves/filters, adjusted for fluid density.
- Centrifugal for higher flow/low–moderate viscosity and smoother operation; positive displacement for high viscosity, accurate metering, higher pressures, or when flow must stay steady as pressure changes.
- ANSI process pumps are for clean/process fluids and standard chemical-duty applications; self-priming trash pumps are built to handle air entrainment and larger solids for dewatering/wastewater.
- Match wetted materials to the fluid chemistry, temperature, and abrasiveness (e.g., 316 SS for corrosion resistance; ductile iron for general service; hardened materials/coatings for abrasion).
- Often yes on the discharge side to control flow (within limits), but avoid deadheading too long (heat buildup); never throttle suction, use a valve only for isolation.
- VFD speed control is usually most efficient; throttling works but wastes energy; bypass recirculation may be needed to maintain minimum flow.
- Use viscosity-corrected curves or consider positive displacement; expect reduced flow/increased power and ensure suction piping supports high-viscosity feeding.
- Define solids size, concentration, hardness, and shape; choose solids-handling hydraulics, slower speeds, abrasion-resistant materials, and appropriate clearances.
- Select compatible metallurgy/coatings, control pH/chemistry, reduce velocity in corrosive service, manage solids, and use wear parts designed for abrasion.
- Alignment, lubrication, seal support/flush checks, strainer cleaning, vibration/temperature monitoring, and verifying operation near BEP and above minimum flow.
- Best Efficiency Point is where the pump runs most efficiently with lowest vibration; aim to operate near BEP to improve seal/bearing life and reduce energy cost.
