: : STRUCTURAL
The DMF type pump is being installed toward vertical direction and is divided into suction, guide casing, 90º discharge bent pipe & middle column pipe,motor plate.
The impeller is a mixed flow type impeller, all the open type, fight lock type can be used according to total head, the main shaft is protected by shaft protective sleeve, and is being connected with the screw coupling or division coupling. The bearing is composed of roller bearing or ball bearing, which is supporting the total weight & shaft thrust power thus and so selected the best bearing, the middle bearing is also guaranteed no oiling with a long life span by selecting THORDON bearing.
: : FEATURE
For underwater installation, it has vertical pipe type casing, which was separated toward circumferential with the following features.
1) Lesser friction damage because of suction pipe length is shorter.
2) Minimized space and installation cost for its space is narrower.
3) There is no uneasiness of touching water for the motor device is located at the top
4) Remote & automative operation is available for there is no vacuum device to operate.
: : USED
1) Agricultural irrigation.
2) Water level controller at dam.
3) Flood control and protection against heavy rain.
4) Circulation of cooling water at power plant.
5) Sea water pumping and industrial water supply.
