Reciprocating pumps include plunger, diaphragm, and piston pumps. The high-density solids pumps which can be used in the widest range of situations are piston (or reciprocating) pumps. They can be realized as single-cylinder or two-cylinder pumps. In the latter case, power is transferred to the material via delivery pistons working in push-pull ...
The popular elastomers for pump tubing are nitrile (NBR), Hypalon, Viton, silicone, PVC, EPDM, EPDM+polypropylene (as in Santoprene), polyurethane and natural rubber. Of these materials, natural rubber has the best fatigue resistance, and EPDM and Hypalon have the best chemical compatibility.
A concrete pump is a machine used for transferring liquid concrete by pumping. There are different types of concrete pumps. There are different types of concrete pumps. A common type of concrete pump for large scale construction projects is known as a boom concrete pump, because it uses a remote-controlled articulating robotic arm (called a ...
Putzmeister was founded by Karl Schlecht in 1958. [3] Schlecht designed a mortar machine based on his diploma thesis at the University of Stuttgart. [4]In 1986, Putzmeister 52Z's were used in the Chernobyl nuclear accident, pumping over 300,000 m 3 (390,000 cu yd) of concrete to entomb reactor number 4, setting a world record at the time for volume pumping.
A mixture of pyroclastic material, rocky debris, and water produced in a volcanic eruption and known as a lahar; A mixture of bentonite and water used to make slurry walls; Coal slurry, a mixture of coal waste and water, or crushed coal and water [5] Slip, a mixture of clay and water used for joining, glazing and decoration of ceramics and pottery.
The acquisition was a strategic approach to expanding the company's own building materials portfolio. The company invested around 10 million dollars in a new technology center in Beachwood, Ohio, in 1977, which focused on concrete analysis and testing. [2] During the 1980s, the construction chemicals business underwent various transitions.
Although metering pumps can pump water, they are often used to pump chemicals, solutions, or other liquids. Many metering pumps are rated to be able to pump into a high discharge pressure. They are typically made to meter at flow rates which are practically constant (when averaged over time) within a wide range of discharge (outlet) pressure.
Inductive pumps have been used in many different applications such as the following: Industrial chemical feed systems; Water Treatment chemical injection process; Oil bearing lubrication of industrial pump and motor bearings (Block and Budris, 2004) Automotive pumping systems i.e. fuel pumps, vacuum pumps, exhaust treatment pumps etc.
