How Long Does a 2HP Pump Usually Last?
A well-built 2 hp water pump should last 10 – 20 years. Industry guides put the average span for submersible and solar units at 8 – 15 years, with many systems reaching two decades when water is clean and routine checks are done. Several factors shorten or extend service life: Water quality – Sand or high iron grinds seals and impellers; wet ends made of stainless-steel...

What are the Benefits of a 2 HP Water Pump?
A 2 hp motor (around 1.5 kW) is in between the small and the medium range, and it has a number of obvious advantages: More head – Submersible models reach 400 – 700 ft of total dynamic head, enough for deep domestic wells and many hillside sites. One stainless pump is rated for 427 ft, and another bronze unit still delivers flow at 700 ft. Higher flow...

Which Solar Pump is Better, AC or DC?
No type of motor is superior to the other in all applications; depending on the power needs, location and cost. DC pumps are pumped directly off the panels, thus no inverter losses. They start at low sunlight, suit small livestock troughs and household tanks, and handle heads up to about 150 m in the 0.3–2 kW range. Fewer electronic parts mean lighter weight and easier field service,...
