"The Papa Pump was designed with simplicity in mind and the kit includes everything you need to install to your system and start pumping water!

You should be confident that with basic skills you will be able to self install ram pump.  You may need a little help with digging trenches and laying pipes, etc. but many farmers and land owners have the equipment and experience to do this work themselves."

Phil Selwyn - Inventor and Technical Director

UK Site Survey

Surveying your own site is something you can do quite easily if you have a basic understanding of farming or land management. At Water Powered Technologies we will be happy to assist by looking at your site with online maps and advise on optimum tank and pump locations. However, not everyone has the time or would just prefer our expertise to survey your site. In which case, we offer a Site Survey Service if you live in the UK...

Pipework, Trenching and Installing Chambers

Laying Pipes and Trenching

We recommend burying your pipework if possible to protect from damage, but DO NOT FILL IN YOUR TRENCH BEFORE TESTING THE SYSTEM - make sure there are no leaks, as this will affect the efficiency of your system.

Please use the recommended pipe specifications as below.  The pump is designed for a 2" supply pipe and a 1" (32mm MDPE) delivery pipe.   USE 2" THREADED STEEL PIPE FOR THE SUPPLY PIPE - This is absolutely essential for the efficiency of the pump.  Full details on supply pipe specifications are in the Installation Manual (page 11).

Tanks and Chambers

You can use any solid chamber for your Supply Tank and Pump Chamber but if available, we recommend bedding 1.2 metre diameter concrete rings on a concrete base - this can house up to 3 Papa Pumps. We also recommend using lids or covers to keep animals/debris out the chamber.

Storage Tanks can be bought in a range of sizes from your local agricultural or building merchant. Alternatively you can use a pond or lagoon for storage.

Full instructions and guides can be found here or in the Installation Manual.

Does the pump chamber need to be a concrete ring?

We recommend using concrete rings wherever possible because they provide excellent protection and the ample space for installing and maintaining your pump.

However, in some situations, cost and availability can be prohibitive and alternative materials or constructions can be used for your pump chamber.  The important thing is to leave enough space to work and to give the pump some good protection.  It is also recommended that a good lid or cover is fitted to keep out debris and animals.  It will also suppress any noise from the pump.

bspt or npt threads?

The Papa Pump's 2" connections conform to BSPT (British Standard Pipe Taper) but in some of parts of the world NPT (National Pipe Taper) is the local standard fitting.  In these cases just let us know when you order your pump and we'll add free BSPT/NPT adaptors to the kit.
