Application

SKC self-priming rotodynamic pumps with side channel and centrifugal impeller before the first stage serve to pump liquids within the corrosion resistance limits of materials used for their construction. Liquid can contain trace amounts of non-abrasive solid particles up to 0,5 mm in size. SKD is a self-priming pump. it is only necessary to flood the pump it self, without necessity to flood suction pipeline with liquid. SKC / SKD pumps are manufactured in wide range of material versions, including bronze and cast steels.

Pumps can pump liquid with a minimum excess of pressure over boiling point. Small NPSHr net positive suction head in pumping system and very good self-priming ability are of particular advantage. They are designed to pump crude-oil derivative fuels and liquid propane-butane mixture, without gaseous phase fraction.

SKC/SKD pumps are used in:

• LPG filling stations
• industrial systems

SELF-PRIMING LIQUID RING PUMP and SPLITCASE

Application

SKA type self-priming centrifugal, pums with side ring channel and open impeller, are designed to pump liquids within the corrosion resistance limits of material use for their construction. the biggest advantage of SKA pumps is their self-priming ability, which eliminates necessity to flood suction pipeline with liquid.

• waterworks system
• individual households
• waterworks automatic systems
• industry

SM self-priming pumps are designed for pumping non-aggressive liquids, except fuels, within the corrosion resistance limits of materials used for their construction and liquid containing trace amount of non-abrasive solid particles of up to 0,5 mm in size. The advantage of SM pumps is their ability to automatically remove air from the suction pipeline after their one-time priming with pumped liquid without the need of flooding suction pipeline. SM pumps are by standard equipped with mechanical seal that entirely eliminates leakage of cord sealing lubricant. another advantage of SM pumps is their compact structure, which reduces space needed to install them.

DHV Centrifugal, single stage, double suction, axially sectioned DHV type pumps are suitable for pumping clean or slightly impure (max 20 mg/dm3) liquids of low viscosity and with a temperature of up to 130 c. The DHV pumps are characterized by high rigidity of the hydraulic system, due to two-sided support of the shaft. owing to the impeller mounted centrally on the shaft and water suction carried out on both sides of the impeller, the axial forces within the pump have been reduced to the minimum, allowing the application of a simple bearing system and considerably extending the life of the pump itself. these pumps are characterized by hight efficiency and low maintenance costs. vast array of type series and extensive operating range enable optimal pump selection in accordance with the preset operating paramater.

DHV pumps are used in :

• water supply systems and waterwork
• industry (pressure increasing systems, cooling system, process water circulation systems)
• thermal-electric power stations
• industrial cooling systems
