Waterproof pumps type PZ / PSZ made by KSK Ruda Śląska, are used to pump highly polluted liquid with solid up to 50 mm. Drainage submersible pumps type OPZ are designed to pump clean and contaminated water with solid up to 15 mm.
Mud pumps type PZ / PSZ have been constructed basing upon the technical conditions, which can be found in various production centres, especially mines, power plants and refineries. The purposeful resignation of cooling the engine down with a pumped medium allows to use the pumps in extremely difficult conditions. The OPZ series of drainage pumps supplement KSK's offer of pumps whose engine is cooled by a pumped medium.
The waterproof mud pumps are provided with ATEX and can be used in mines’ undergrounds.
The pumps should be installed and used according to technical documentation. The pumps should work with full or part submergence.
