Grundfos SP 3A-33 Submersible Bore Pump
Verified1 review
Grundfos Quality Issues – I had a Grundfos SP2A installed in 2003 that failed in 2007. The Grundfos agent advised us to try a larger pump, so we had them install an SP3A-33 in our 100m bore. The pump was designed to pump up to a tank on a hill, producing a total head of 160 m. While the water quality is fairly soft and suitable for stock and garden use, the pump has again failed.
Upon inspection, it was found that a weld had failed on one of the 3 straps, designed to hold the 33 stages together. A weld that attaches the drive hub to one of the 33 impellers also failed. The combined failures of these welds, has contributed to a failure of the drive shaft, between the motor and the pump. The pump has to be replaced.
Grundfos failed to satisfactorily respond to the problem, simply offering a heap of unrelated excuses. It appears that Grundfos have quality and durability issues with their products. Several farmer's in our area have reported experiencing similar problems with Grundfos bore pumps.
I would say that while they charge a premium price for a product, which they claim is very durable, this is not the case. A far cheaper pump costing a third of the price, that only lasts half the time, might be a better option.
Your service manager contacted me after I went online to express my frustration at the lack of support. At the time of writing this response, the contact and offer of assistance has not been followed up.
Due to the cost of replacing the control box and electronics, it was decided to use another SP3A pump. The motor cable connection kit, supplied with the replacement pump, was not compatible (suitable) with the size of the drop cable in the bore. This necessitated field modifications to the connector, in order to get the pump operational.
This connection to the motor cable is critical, and the size of the drop cable should be noted and taken into account at the time a pump is dispatched from the factory. Modifying improper connections are difficult in a paddock, at a remote location.
