New & Used Industrial Pumps For Sale

An industrial pump is a machine that moves fluids, liquids, slurries, gases or combinations, through a process. Pumps are specified by the fluid’s physical properties (viscosity, density, temperature, corrosiveness, solids content), the required flow rate, the pressure they need to generate, and the environment they operate in. The two main pump categories are dynamic (centrifugal) pumps, which use a spinning impeller to add velocity to the fluid, and positive displacement pumps, which use pistons, gears or other mechanisms to trap and displace fixed volumes of fluid per cycle.

Well-maintained industrial pumps typically last 15-30 years. Casings and impellers are long-lived; mechanical seals, bearings, wear rings and gland packings are routine consumables replaced every 6 months to 5 years depending on duty. Pumps handling abrasive or corrosive fluids will have shorter wear-part life than those handling clean water or non-reactive fluids.

Industrial pumps underpin virtually every continuous process in manufacturing, utilities, food production, chemicals and water treatment.

• Continuous, high-capacity flow: industrial pumps deliver sustained flows from millilitres per minute (metering) up to thousands of cubic metres per hour (large water pumps).
• Consistent pressure generation: pumps deliver predictable head/pressure for pipeline transport, spray applications, filtration and heat exchange.
• Fluid-specific design: specialist pumps handle slurries, viscous fluids, sheer-sensitive products, corrosive chemicals and sterile pharmaceuticals.
• Efficient integration: modern pumps with VFDs, SCADA connectivity and predictive-maintenance sensors integrate cleanly into automated plants.
• Wide performance range: a single pump family often covers a 10:1 flow range via trim, speed and impeller changes.

Industrial pumps are excellent candidates for used-market purchase, the mechanical designs are mature and refurbishment is routine:

• Material cost savings: quality used pumps cost 40-60% less than new, significant when buying multiple units or high-spec alloy pumps.
• Immediate availability: new specialist pumps (sanitary, chemical, cryogenic) can have 8-20 week lead times. Used stock is often available within days.
• Refurbishment is routine: pumps are designed to be stripped and rebuilt. Replacing seals, bearings and wear rings returns most used pumps to as-new condition.
• Proven performance: a pump with documented running history has demonstrated its reliability on a real duty.
• Strong aftermarket: Grundfos, Sulzer, KSB, Flowserve, ITT, Alfa Laval, SPX Flow, Wilden, Watson-Marlow all have extensive UK service support.

Centrifugal pumps

The most common industrial pump type. Use a rotating impeller inside a volute casing to accelerate fluid, converting velocity to pressure. Suit clean, low-viscosity liquids at moderate to high flows and low to moderate pressures. End-suction, split-case, multistage, submersible and vertical inline designs cover different duties.

Positive displacement pumps

Trap fixed volumes of fluid each cycle, generating pressure by displacement. Essential for viscous fluids, high-pressure applications, precision dosing and shear-sensitive products. Sub-categories include gear, lobe, piston, diaphragm, peristaltic, screw and progressive cavity pumps.

Vacuum pumps

Evacuate gases from process chambers and pipelines. Oil-sealed rotary vane, dry-running claw, liquid ring, roots blowers and turbomolecular pumps each serve different vacuum levels and process compatibility. Common in food packaging (MAP), pharmaceutical freeze-drying, vacuum distillation and electronics manufacture.

Sanitary and hygienic pumps

Designed for food, dairy, beverage, pharmaceutical and cosmetics production. Typically polished 316L stainless steel with sanitary connections (tri-clamp, DIN), CIP capability and 3A/EHEDG/GMP certification. Centrifugal, lobe, progressive cavity and peristaltic variants all feature.

Submersible pumps

Sealed motor-pump units operating fully submerged in the fluid. Common in borehole water supply, sewage pumping, construction dewatering, mine drainage and wastewater treatment. Offered in cast iron, stainless steel and specialist alloys.

Magnetic drive and canned motor pumps

Sealless pumps use magnetic coupling to isolate the motor from the product, eliminating shaft-seal leakage. Essential for aggressive chemicals, ultra-pure processes, hazardous fluids and when zero-emissions operation is required.

Metering and dosing pumps

Precision positive-displacement pumps deliver accurately measured small flows. Diaphragm, plunger and peristaltic designs cover chemistry from hazardous chemicals to food ingredients. See our dedicated dosing units category for the full range.

• Fluid properties: viscosity, density, temperature, solids content, corrosiveness and abrasiveness all drive pump selection. Wrong pump choice is the biggest cause of premature failure.
• Duty point: flow rate and head must match the system curve. Over-sized pumps run off their best efficiency point and wear faster; under-sized pumps won’t deliver duty.
• NPSH (Net Positive Suction Head): required vs available NPSH must be checked to avoid cavitation, the most common cause of centrifugal pump damage.
• Wetted materials: cast iron, 316L stainless, duplex, super-duplex, Hastelloy, titanium and plastic (PP, PVDF) all have specific chemical and abrasion resistance. Verify compatibility with your fluid.
• Seal type: mechanical seals (single, double, cartridge) for most duties; magnetic drive or canned motor for zero-leak; gland packing for heavy slurry. Double-seal designs add safety on hazardous products.
• ATEX rating: flammable liquids, solvents and explosive dust require ATEX-certified pumps. Always verify current certification before purchase.
• Control and drive: variable-speed drives (VFDs) match pump speed to demand, saving energy and reducing wear. Confirm motor, coupling and drive condition on used machines.
•  

• Water and wastewater: raw water transfer, treatment chemical dosing, sludge pumping, distribution and sewage handling.
• Food and beverage: milk, beer, wine, juice, sauces, dough and ingredient transfer with hygienic centrifugal and positive-displacement pumps.
• Chemical and petrochemical: process transfer, reactor feed/discharge, solvent handling and acid/caustic dosing, often with exotic alloy or sealless pumps.
• Pharmaceutical and biotech: sterile transfer, fermentation feed, product filling and CIP/SIP circulation, always with sanitary, documented-traceable pumps.
• Oil and gas: crude transfer, water injection, chemical dosing and drilling mud handling, from small skid pumps to large mainline units.
• HVAC and building services: chilled water, heating water, cooling tower and domestic water pumping.
