Why Mobile and Static Pumps are Important for Construction
The concrete is pumped by diesel or electrically powered static concrete pump, through a fixed 125mm pipeline to the stationary placing boom. The boom is mounted on a steel column of up to 20 meters high. The column is supported by a cross base or a system of floor frames set into the concrete floors. If floor frames are uses the whole column

STAR Serie 8" The trailer STAR Series 8" allow high flow of concrete both in vertical and in horizontal plan; results obtained from research and testing in the yards
Nov 15, 2011 · Use a heat pump to transfer heat between two insulated tanks of gravel. Then use the heat pump in reverse as a heat engine to recover the heat and generate electricity. Cooling 15 tonnes of granite gravel down to -150°C and heating another 15 tonnes up to 500°C is sufficient to store 1MWh of electricity. Round trip efficiency of 72% to 80%.
Pumping of concrete is economical if the quantity of concrete required is more than about 1150 m 3 or uninterrupted supply of concrete is needed over a long period as at the beginning of each period of pumping the pipes have to be lubricated by mortar (at the rate of about 0.25 in 3 per 1000 m length of 150 mm diameter pipe) and also at the end of the operation considerable effort is needed
Most static pumps can move material at least 60 m vertically or 300 m horizontally, though greater distances have been achieved with more powerful pumps. The rate of flow depends on many factors, including the concrete mix, the type of pump, the distance …

CENTRIFUGAL PUMP SELECTION, SIZING, AND INTERPRETATION OF PERFORMANCE CURVES 4.0 PUMP CLASSES Pumps may be classified in two general types, dynamic and positive displacement. Positive displacement pumps are those in which energy is imparted to the liquid in a fixed displacement volume, such as a casing or a cylinder, by the rotary motion of gears,

pumping processes, and or into contractual requirements with third party contractors where pumping is out-sourced. Supervisors, maintenance staff, operators, crew, order takers and other staff involved in any aspect of concrete pumping shall receive adequate and appropriate training on the minimum standards contained within this handbook.
A new method is proposed to estimate pumping pressure based on concrete composition without experimental measurements. Previous studies show that the pumping pressure depends on the interface friction between concrete and the wall of the pumping pipes. This friction is determined by the thickness and the rheology of the boundary layer formed at the interface.
