Pumps - Summit Industrial Products
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 centrifugal pumps (also called non-positive-displacement pumps).
Positive-displacement pumps move a set amount of liquid each cycle using seals or valves. They’re the go-to choice for thicker, high-viscosity materials—like slurries, oils, or adhesives—because they deliver a steady, reliable flow. Centrifugal pumps use rotating impellers to keep liquid moving, making them ideal for high-volume jobs like circulating water, solvents, chemicals, and light oils.
At Centro, we carry a full range of industrial pumps to match almost any process or application. Our selection includes air-operated double diaphragm (AOD) pumps, lobe pumps, submersible pumps, hose/peristaltic pumps, metering pumps, progressive cavity pumps, sealless mag-drive pumps, hydraulic pumps, and a variety of pump control systems.
Whether you’re looking for precision metering, chemical compatibility, or rugged performance, our team can help you find the right pump for the job. Browse our pump categories to compare options, or call Centro for expert guidance on selecting the best pump for your operation.

- 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.
