Suitable for Schwing® pumps

WEAR PLATES AND RINGS

In the pumping unit of a machine, the most important function is represented by the exchange that occurs through the movement of the S-valve; the contact and the seal between the parts is maintained and guaranteed by the wear ring that moves on the relative wear plate. RM® produces wear plates and rings compatible with the main brands of concrete pumps in the market. These components can be made of heat-treated cast iron or steel with tungsten carbide coatings, with very high strength.

DELIVERY BARRELS

Concrete delivery barrels, together with the pistons, pump the concrete from the pump hopper to the distribution pipeline. RM® produces steel barrels with internal chrome plating of constant thickness along the entire length to be compatible with the major pump manufacturers in the market. On specific requests from customers, RM® is able to produce delivery barrels according to drawings.

Chromed delivery barrels

RUBBER PISTONS

The pistons, together with the chrome delivery barrel and the S-valve, are the heart of the machine. RM® produces rubber pistons with a compound capable of withstanding the heaviest duties to which they are subjected. The pistons are made using both the classic technology based on metal cores (generally made of cast iron or steel) on which the rubber is vulcanized, and the more recent technology that involves the use of replaceable caps and guide seals, fixed on supports generally made of aluminium alloys. In the latter case, in compliance with the different design choices, the lightness of the assemblies (about 20% less) can be achieved, which is particularly advantageous for the life of the system.
