- Secure the pump and keep it out of the path of large, mobile equipment.
- Locate the pump as close as possible to the liquid to keep suction lift to a minimum. The shorter the distance a pump has to move liquid, the more volume it will deliver. Longer hoses produce more friction and less volume.
- Check the suction hose for leaks and secure all fittings. Many pump failures are due to a faulty suction hose connection.
- Use the proper hoses. Reinforced hose on the suction side will prevent collapse. Flexible hose is recommended on the discharge side.
- With wet-prime pumps, prime the pump before starting the engine. Even a tiny pinhole in a hose could cause the pump not to prime. When the discharge hose is pinched or clogged, air cannot escape and the pump will not prime.
- Only pump liquids for which the pump is designed.
- Use the proper strainer to prevent clogging and damage.
- Drain the pump before freezing weather.
- Check the suction strainer regularly and keep it clean.
- Pumps should be run at the specified rpm. Higher rpms only provide temporary performance advantages until the engine is damaged.
- Monitor the pump while it's in operation.
Another way to ensure long life from your trash pumps is to invest in quality. "A higher quality construction really makes a difference in the overall life of the pump and how it will withstand the rigors of the jobsite," says Leupi.
Widrick agrees, noting it's important to think long term. "You should invest in high quality and what will have a good resale value down the line," he emphasizes. "Working with a reputable manufacturer is a good start."
