The vacuum pump is a compact liquid ring type pump. Body made from graded CI casting & impeller from SS 304. An filter assembly in the tank, prevent dirt & other foreign matter from following water & air in to the pump.. frame is mounted on a wheeled chassis for easy movement.

The key to the use of this method is the dewatering of concrete by vacuum process. Surplus water from the concrete is removed immediately after placing and vibration, reducing the water : cement ratio to an optimum level. Therefore, adopting the Windsor method facilitates use of concrete with better workability than what is normally possible.
A lowered water : cement ratio automatically leads to a noticeable improvement in almost each of the concrete properties.
THE OPERATION
In order to obtain a high quality concrete floor using this method, it is essential to follow the various operations in the correct sequence. Initially, poker vibration is essential, especially at the panel edges. This results in proper compaction of the concrete and hence elimination of voids and entrapped air.

Suction Mat of special grade multilayered polymer sheets alongwith reinforced distance cushions on the Filter Pads ensure sufficient crosssectional area to squeeze out and remove excess water from the concrete. This design is a prerequisite for effective dewatering.
