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.
