I had an urgent request from one of our depots for ten 110v 2” submersible water pumps for hire and all of our fleet was utilised. I called Obart in the afternoon to see if they could help.

Not only did they have the pumps in stock and got them dispatched that same afternoon, they also engraved our plant numbers on the pumps before despatch saving us a lot of time as they were ready to go on hire as soon as we got them.

The pressure pump was delivered very quickly in a very protective box. On inspection the quality of the pump was exceptionally high with a good finish, good quality fittings and gauge and the price was very reasonable. It was easy is to install and operate with the gauge giving a good stable reading and the holding valve operating correctly.
