A submersible water pump performs differently depending on the water source. Drawing water from a deep well requires a different approach than pumping from a garden pond. A submersible clean water pump placed in a well must handle the full static head from the water surface. A submersible irrigation pump in a shallow pond enjoys a shorter lift but may face algae growth. The operator of a submersible water pump needs to adjust the pumping strategy according to each source.
Well water tends to be cold and free of organic matter, which benefits a submersible water pump seals. A submersible garden pump used in a well runs cooler because of the low water temperature. Cooling extends the life of the motor windings in a submersible water pump. However, well water often contains dissolved minerals that leave deposits on the impeller of a submersible fountain pump. These deposits gradually reduce the clearance between the impeller and the volute. A submersible irrigation pump used in hard well water needs periodic descaling.
Pond water presents a different set of challenges for a submersible water pump. Algae and fine sediment in a pond clog the intake screen of a submersible clean water pump faster than well water. A submersible fountain pump sitting in a pond must handle floating particles without jamming. Some pond owners place their submersible water pump inside a perforated bucket to pre-filter the water. A submersible drainage pump used in a pond should not draw water from the very bottom, where sludge accumulates. Raising the intake of a submersible water pump by 10 centimeters reduces sediment ingestion.
A storage tank or cistern offers clean water but limited volume for a submersible water pump. The operator of a submersible garden pump must monitor the tank level carefully. Running a submersible irrigation pump until the tank runs dry damages the pump instantly. A submersible utility pump without an automatic shutoff requires human attention during use. Setting a timer or using a visible water gauge helps the owner of a submersible water pump avoid dry running. A submersible waterfall pump used from a tank needs the same watchful care.
Water temperature also affects the performance of a submersible water pump. Warm water reduces the viscosity and provides less cooling to the motor of a submersible water pump. A submersible clean water pump running in a shallow, sun-heated pond overheats faster than in a cool well. The thermal protector of a submersible fountain pump may trip sooner during hot summer afternoons. Shading the water source or running a submersible irrigation pump during early morning hours keeps temperatures lower. Each water source demands specific attention from the user of a submersible water pump. Understanding these differences ensures a submersible water pump operates reliably across all garden watering and draining tasks.
