Pump repair services repair and rebuild used pumps. They differ in terms of capabilities, but generally repair pumps to their original specifications. Services offered include bench repairs, field repairs, calibration, documentation, pick-up and delivery, and installation and startup. Bench repairs are made at authorized service centers. Field or on-site repairs are made at the customer’s location. Pump calibration services compare a pump’s output and accuracy to published standards and established values. Pump repair services that provide documentation may include "as found" and "as left" information, as well as calibration certifications and recalibration notifications. Pump pickup and delivery services can help customers to minimize downtime. Pump repair services that provide installation and training are also commonly available.
Some pump repair services employ personnel who are certified or approved for original equipment manufacturer (OEM) or warranty-repair work. Others provide preventative maintenance or preventive maintenance, a term which describes contracts and services for the performance of proactive maintenance in order to prevent pump problems. Pump repair services that overhaul, rebuild, and remanufacture specialized products are also available. Services offered may include rental or lease agreements, replacement or exchange programs, spare parts inventory, troubleshooting services, and upgrades. Pump repair services that maintain a spare parts inventory carry replacements in-house, thus eliminating the added time that ordering and shipping parts would require. Pump upgrade services enhance the performance of an existing product by adding a new component.
Pump repair services specialize in the repair of industrial liquid-handling pumps, heat pumps, and vacuum pumps. There are many types of liquid handling pumps, but two main technologies: dynamic and displacement. Dynamic or displacement pumps impart energy into the fluid, frequently increasing its velocity to a level greater than that allowed by the fluid outlet port. Displacement pumps are distinguished by their comparatively high-pressure capabilities. Both types of industrial liquid-handling pumps are designed to work with specific fluids and/or applications. Examples include chemicals, cryogenic materials, foods or beverages, fuel or oil, high-temperature fluids, high-viscosity fluids, hydraulic fluid, medical or surgical fluid, refrigerants, sewage or sludge, slurries, and water or wastewater. Heat pump repair services and vacuum pump repair services are also commonly available.
