Dear Madam, dear Sir, for a medium size project we need a stationary pump, that is able to push the concrete aprox 10 m high (when it comes out of the pump, angle aprox 35 degree) and than some 150 m horizzontal. Is this pump able to do so? What is the maximum time interval between filling of pump, in order to avoid that the concrete is hardening in the pipes? Temperature at casting time aprox. 28 degrees celsius, air humidity aprox. 60 - 80 %. What is the best slump?
