Abstract: Multistage centrifugal pumps are cleaned using ultrasonic energy and without disassembling the pump. The system can be at a permanent installation where the pump is brought for cleaning. The fully assembled pump is submerged in a tank of fluid and cleaning solution is circulated through the pump while ultrasonic energy is applied to the tank. Alternately, a portable pump cleaning system is taken to the site where the pump is working, such as a well site. The pump is cleaned by circulating a cleaning fluid through the pump while ultrasonic energy is applied to the pump housing. Still further, ultrasonic energy may be applied to the pump housing while it continues to pump a working fluid. Flow resistance through the pump is monitored to determine when the cleaning process is complete. In all three applications, disassembly of the pump is unnecessary, providing a major savings in time and money.

Abstract: A submersible pump test bench capable of testing multiple lengths of submersible pumps. The test bench includes a series of trolleys that may be moved along, added to, or removed from a rail depending on the length of submersible pump to be tested. The test bench further includes a hose handler for redirecting a length of hose connecting the submersible pump to a broader hydraulic circuit. In certain embodiments, the hose handler includes a rotating sheave or similar structure that redirects the hose back on itself, providing a length-multiplying effect.
