Pumps - Innomag/Flowserve
Industrial pumps move liquids from one place to another, whether you’re handling water, chemicals, or thick, heavy fluids. Most pumps fall into one of two main categories: positive-displacement pumps and cen...
Non-metallic centrifugal seal-less mag-drive pumps offer leak-free, corrosion-resistant fluid handling for aggressive chemicals, acids, and solvents in industrial applications such as chemical processing, water treatment, and electronics manufacturing. Utilizing a magnetic drive system instead of mechanical seals, these pumps eliminate seal failure risks and minimize maintenance in hazardous or high-purity environments. Constructed from materials like polypropylene or PVDF, they provide reliable, safe, and efficient operation where metal pumps may corrode or contaminate process fluids.
Sealless magnetic drive pumps are a type of pump that uses magnets to drive the impeller rather than a sealed shaft and bearings. This design eliminates the need for a mechanical seal, making them ideal for use in applications where a bearing or seal failure could release hazardous or toxic fluids. Centro’s selection of sealless magnetic drive pumps is available in various sizes and materials to suit your particular application. With our easy-to-use online purchasing system, you can be assured that you're getting the best possible pump for your money.
Pump Parts & Servicing products involves the maintenance, repair, and replacement of key pump components to ensure optimal performance and longevity. Regular servicing helps prevent breakdowns, reduces downtime, and extends the life of pumps in various industrial applications. It provides efficient operation, minimizes costly repairs, and maintains consistent fluid handling performance.

- 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.
