The SP100.23.360D is the top model in the TRUEMAX A9 stationary concrete pump range — a high pressure concrete pump built to push concrete to the upper floors of high-rise towers. It delivers up to 100 m³/h and reaches 23 MPa concrete pressure, the highest in the range, driven by a 360 HP Cummins engine. That pressure is what matters on tall buildings: at high gear it trades volume for the pressure needed to lift concrete up a long vertical riser, while at low gear it pumps the full 100 m³/h for faster placement at lower lifts.
The brochure positions the SP100.23.360D for high-rise (high building) concreting — the tallest work in the stationary-pump range, above the mid-range SP90.18.253D and the small SP50.10.82D. On a high-rise it sits at ground level and feeds a riser pipeline up to a placing boom on the working floor. Like every TRUEMAX pump it is built and tested in our own factory in Haining, runs an open hydraulic circuit, and is backed by ISO 9001:2015 and CE certification and service in more than 120 countries.
1. High-pressure pumping to 23 MPa — The highest concrete pressure in the range — what lets the SP100.23.360D push concrete up the long vertical risers of high-rise towers, with an S-valve and strong pumping system suited to mixes from C15 to C70.
2. One-button high / low pressure switching — Switch between high pressure for height and high output for volume at the touch of a button, matching the pump to the lift in front of it.
3. One-button twin piston return — Both pistons return into the water box at the touch of a button, which makes changing the delivery cylinders and wear parts faster.
4. Hydraulic integration block — A compact valve manifold shortens the oil passages, lowers internal flow resistance and keeps the hydraulic system temperature stable under sustained high-pressure work.
5. Dual-drive lubrication — Manual plus fully-enclosed automatic relubrication keeps the moving parts greased and extends service life.
6. Chrome-plated delivery cylinder — The Φ200 mm cylinder bore is chrome-plated for a service life above 100,000 m³, with the cutting ring and glass plate made from rigid alloy — important under the high pressures of high-rise pumping.
7. Cummins diesel with energy-saving control — A 360 HP air-cooled Cummins engine runs independent of site power, and the power-matching algorithm raises pumping efficiency by up to 15% and cuts fuel use by up to 10%.
8. Intelligent control and protection — Real-time monitoring, self-diagnosis that cuts fault-finding time by up to 70%, and automatic overload and low-fuel protection guard the engine and oil pump.
