Putzmeister Thom-Katt TK 20 Tier 4I Trailer-Mounted Concrete/Shotcrete Pump

A rugged, high-pressure pumping system, the TK 20 is Putzmeister’s answer for midrange pumping requirements. With output up to 17 yd³/hr, it has superb control for the most critical geotechnical and compaction grouting applications. Ideal for wet-process refractory, underground and civil work, it can be fed by ready-mix truck, refractory mixer or its optional detachable mixer.

Work longer with a bigger fuel tank (up to 38 gal/144L) on our wide, high-strength trailer (74.5 in/1.89m), built for maximum towing stability.

Hydraulically operated, the optional 13 cubic foot detachable mixer provides productivity when handling large ammounts of material. The mixer provides the option to feed the hopper with site mixes ore pre-packaged materials.

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.

Discover the convenience of our simple and highly reliable hydraulic control system. Mounted on a compact block atop the hydraulic tank, it offers easy access and lets you service the pump without draining the oil tank.
