Different Types of Concrete Pumps and Selection Process

Since these pumps pump concrete at a rate lower than the boom pump, they are best suited for projects that require a smaller amount of concrete to be poured. 3. Specialised usage pump: Used for specialised job sites such as mines and tunnels, this type of pump is not used often because of its very high cost and extra specialised mechanism.

What is Pumped Concrete? Types of Concrete Pumps and Selection

Apr 26, 2016  Concrete pumps are selected based on two primary parameters, the maximum desired volumetric output of concrete per hour and the peak pumping pressure, p. A nominal output of 30 m3/h is considered sufficient for routine concreting operations related to most civil engineering applications.

Mar 21, 2016  Concrete pumps can be either truck- or trailer mounted and range from small units, exerting pressures from 250 to 300 psi and outputs of 15 to 30 yd 3 /hr, to large units, exerting pressures of 1,000 psi and outputs up to 150 yd 3. The effective capacity of a pump depends not only on the pump itself but also on the complete system.

Benefits of Using Concrete Pump in Construction Works

Concrete pumps required less amount of water compared to other concrete pouring techniques. This helps prevent concrete from getting the shrink or seeing cracks once set-up. And this ultimately preserves the concrete’s inherent strength. Stronger concrete structures incur less repair and maintenance cost in the long term.

Hydraulic Ram Pumps - USDA

The basic principle behind ram pumps is to use a large amount of water falling a short distance to pump a small amount of water to a higher elevation. Typically, only 2% to 20% of the water flowing through a ram pump system will actually be delivered to the storage tank or trough. The remainder is overflow and directed back into the stream.

Pump Station Design Guidelines Second Edition

The most important part of any pump selection is first determining the system curve. This means, at the very least, the flowrate and head that will be required of the pump must be identified. Often this is the first mistake made in the selection process. In many potable water booster stations, the flowrate is determined by a downstream demand.
