12v Shurflo Pump - Smart Sensor Water Pump - A buyers guide

Shurflo water pumps are used throughout the world and are highly regarded by RV, caravan and boating enthusiasts. Shurflo pumps are highly reliable and can be mounted in any position. With thermal protection and can be run dry for short periods without damage. Shurflo pumps are quiet 12v pumps, self priming, have a built in check valve and internal by-pass and boast a very credible 3 year limited warranty.

How do the Smart pumps work?

A 12v Smart pump will adjust the outgoing pressure and flow to match the needs of your plumbing system. This means the Jabsco Parmax Freshwater Pumps and Shurflo freshwater pressure pumps which are smart sensor pumps, do not need an accumulator tank since the Smart sensor pumps will speed-up and slow-down as required to meet the demand for water.

What choices do I have if I am replacing a Shurflo or Jabsco 12V pump?

If you are replacing your 12v water pump in your caravan or boat there are cheaper options on the market than the Shurflo or Jabsco pumps but dont expect pumps like the FL pump range which are a much much cheaper price option to operate the same as the Smart Sensor Pumps.

The Smart sensor technology is built into the Jabsco Parmax and Shurflo freshwater pump ranges.

The FL style diaphragm pump range are excellent pumps which operate at one speed and therefore require the addition of an accumulator tank to accumulate the excess pressure in the system. The result if not well matched is a noisy pump and eventual pressure switch failure which alot of people mistake for pump failure.

An FL pump with an accumulator tank will work very effectively and is a cheaper option for most but do not expect the FL pumps used on their own without an accumulator tank to be comparative to the smart pumps like the Jabsco or Shurflo Smart Pumps. Browse Water Pumps Now full range of 12v pumps.
