The pump type SC VP (Single-vane Concrete Volute Pump) is a vertical dry pit pump, single stage with volute pump casing of pre-fabricated concrete material. The pull-out unit of the SCVP is equipped with an single vane impeller design. The material of the metal PUIl-OUt unit depends on the pump liquid and is available in various materials. The

Benefits of CVP and pre-fab concrete volute pumps | Rotaserce

The first concrete volute pump was built in 1935 and is still in good condition. The big advantage of concrete volute pumps is that there are almost no maintenance costs on the volute part. In addition, the concrete construction ensures a very solid foundation of the pumps and contributes to …

Concrete Volute Pump - Flowserve

• A removable, metallic pump pull-out unit is located within a concrete volute. • Below the volute, the suction bell is connected to a preformed intake suction box. All are prefabricated concrete elements. • A manhole permits impeller inspection without removal of the pump unit. • The bearings and sealing systems are easily acces-

ANDRITZ vertical volute pump VVP series

of efficiency. The volute casing is manufactured as a concrete or metal volute. The metal volute is a welded structure consisting of several segments and can be embedded in concrete as an option. This design is used primarily for larger delivery heads if a solution with a concrete volute is no longer feasible due to strength requirements.

Volute casing pumps

Volute casing pumps HVBW pumps are designed for pumping of clean liquids, evenutally lightly polluted by me-chanical impurities within 3% of liquid volume and with maximum grain size of 0,3 mm. The temperature of pumped media can vary from – 20 °C to + 180 °C, operational pressure to 2,5 MPa and density to 1050 kg.m3.

US4076450A - Double volute pump with replaceable lips

Volute pumps are frequently used for abrasive liquids such as in the transportation of aqueous slurrys of finely divided coal and similar materials. Since pumps for such purposes are very large, they are ordinarily made as double volute pumps to minimize radial thrust. When pumps are used for abrasive materials, the wear on the pump occurs primarily at the volute lips.

ANDRITZ Concrete volute pumps CVP series

shaft pumps, concrete volute pumps also have an inlet bend, which guides the water optimally to the impeller. Another essential difference is the much shorter dis-tance between the center line of the impeller and the discharge pipe. This results in a very compact design, less construction depth being required, and reduced construction costs.

A new pump station to drain flooded fenland - ScienceDirect

May 01, 2007 · Concrete volute pumps provide the capability to satisfy the full range of pumping heads and give a minimum of 50% maximum design flow at the maximum 1 in 200 year high tide event. This option has the advantage over other designs considered in that the total motor power is less, thereby reducing the electrical and secondary power costs.

Concrete volute pumps: technology review and improvement

Nov 26, 2012 · When pumps need to deliver large water flow rates (typically more than 5 m 3.s −1), concrete volute pumps (CVP) offer an interesting alternative to standard vertical wet-pit pumps.One of the major advantages of CVP is its simplicity in terms of design, manufacturability and maintainability.
