We have recently added Putzmeister SP11BUR pumps to our hire fleet. These pumps are used to pump a variety of materials including flowing floor screed, grout and concrete repair material material. In addition they can mix, pump and spray fireproofing material, external render and sprayed concrete repair material. The SP11BUR is a very versatile pump, indeed.
The initial contract completed by the first of our SP11s was pumping Lafarge’s Gyvlon flowing floor screed for a new build private house in Essex. Approximately 7.5 cubic metres of the screed was pumped on top of the house’s underfloor heating pipes. The levels were checked and the material was then dappled, once in each direction. The dappling technique is used to ensure a good surface for the finished flooring material.
The SP11 can pump up to 15 cubic metres per hour but is only really likely to need this output when pumping large floors in say hospitals, schools or offices. The hydraulic controls allow the pump to operate at much lower outputs and these are required on the smaller floor areas of domestic buildings. On this particular contract the pump was operating at less than one quarter of its maximum capacity.
On completion of the contract all parties were satisfied. The main contractor for the project, Jomana Ltd, was pleased with the quality of the floor that had been laid and being more familiar with traditional semi-dry sand and cement screeds, was very impressed with the speed and easy of laying the materials. At Camfaud, we were very happy with the first outing our our new Putzmeister SP11BUR pump.
