33 Series DC Diaphragm Pump 12V/24V 3.0GPM 45PSI (12 Volts)

Decent Seaflo pump. The pump itself is very quiet & is good that its self priming. Was very easy to wire up and connect to water lines. Would buy again

We bought this pump as a temporary fix for an ‘over the bath’ style shower mixer with low performance in a house we’re renting. The system in the house has a conventional loft based cold water header tank with a hot water cylinder heated indirectly by a gas boiler. We’ve connected the pump between the mixer shower output and the rose hose via an extra length of standard 10mm shower hose. We’ve bought a switch mode 12v 10amp power supply mounted outside the bathroom so that there is only a 12v lead with a 12v pump switch in the bathroom. It works brilliantly! It’s not any more noisy than a typical impeller type shower pump. It produces a nice strong stream of water, perfect for a good shower! We’ve built the pump into a small MDF enclosure positioned next to the mixer end on the bath. We’ve added some rubber feet to the mounting to improve the vibration. For good measure we’ve installed the supplied inlet filter although I don’t think it’s totally necessary for this type of installation. Basically this is a great pump for this type of temporary system. I would use it again!

Brought this to run water out of a tank in my valeting van and it's perfect. Easy to run and install, gives plenty of power even when placed 10cm above the water line. It's quite and I've had it running for about 4 hours a day for the last 3 weeks, not problems. Can imagine this being used on a boat/rv with no issues

My pump lasted 4 months and failed. I took the pipes off and smoke came out of the water inlet. Something was very seriously wrong with mine. What a waste of money and poor quality.

Monster and build like a tank which the Germans are very good at!

Very good price and so far working well.

This pump is much better than the smaller flow rate version. It as better inlet and outlet connection point. And it is so quite hardly notice it as switch on. Looks to be well built and was easy to connect to the 12 volt system.

While not the most expensive in its class, costing over £60 it is not the cheapest either. For this money I expected better. Installed and running light duty on a shower in a camper RV. It is quiet in operation, economical on power consumption and delivers good pressure. At 3gpm it was good for the purpose for which it was used. However, after only a year of opporation the presure switch malfunctioned causing the pump to be unreliable. Examination proved it to be the electricle contacts inside the switch so it needs to be replaced. The cost of replacing the pressure switch is uneconomical so renders the pump useless. Disapointed in what is otherwise a good unit
