Putzmeister Thom-Katt TK 7 Trailer-Mounted Concrete/Shotcrete Pump

Putzmeister’s TK 7 is ideal for wet-process refractory applications. Its high performance, up to 7 yd³/hr, is coupled with the low operating costs of S-Valve pumps. Critical for safety, the pump is reversible at any point in the stroke, a feature not offered by mechanical pumps.

Putzmeister Advantages

Click the tab(s) below for more information.

Count on our reliable S-Valve for strong, long-lasting performance. A gradual reduction from the hard-chromed material cylinders to the outlet ensures even flow and longer life. Few wear parts, a single seal surface and hard-faced S-Valve and wear ring mean lower operating and replacement costs.

The control box provides real-time presentation of pump information, diagnostics and an emergency run mode. This feature allows the operators to make sure their pump is operating at peak performance. As always, depend on electric cycling for reversibility at any point in the stroke and to relieve line pressure.
