Type OG
Qmax=375m3/h – Hmax=260m
APPLICATION
The OG type pumps are designed for deep mine dewatering. The parameters cover the range required in this application: capacities of hundreds cubic meters per hour and heads up to 1300 meters.The robust design of OG pumps is adequate for adverse operating conditions typical for mine dewatering.The pumps are designed to stand increased external loads and the presence of mechanical and chemical contaminations in the mine water.
For the sake of those design features the OG pumps, beside the basic application in deep mine dewatering are also applicable in other industries, where there is a need for pumping contaminated fluids, such as:
steel industry
cement and lime plants.
DESIGN
OG are horizontal, stationary, multistage, ring-section pumps. The delivery flanges are directed vertically upward suction flange is directed horizontally, left or right according to the needs. Closed impellers and vane diffusers are applied. The axial thrust is absorber by a balance disk. Two alternative kinds of bearings can be applied: oil lubricated slide bearings or grease lubricated roller bearings. The shat seal can be sealed by a gland or mechanical seal.
MATERIALS OF CONSTRUCTION
The materials of construction for the OG pumps are selected accordingly to the handled fluid. There are three standard material versions:
basic – for water containing no contaminations
wear-resistant – for water containing solids
salt-resistant – for chemically contaminated water with solids presence.
Special material versions can be selected for handling non-typical fluids.
