Thanks to the reciprocating movement of the plunger, the working medium is directly sucked in or pumped out. Since the plunger and seal are in direct contact with the fluid, the correct choice of plunger material and seal type will ensure more ideal pump performance during operation.
The outlet diameter and the inlet diameter are the same. SKF bearings, a world famous brand, ensure more stable operation.
An automated system of equipment for accurately dosing certain chemical reagents into the water being treated (“source water”). The main task is “accurate, continuous, automatic” dosing of reagents, replacing the unstable and ineffective manual method.
The length can be individually adjusted from 450 to 1000 mm depending on the depth of the customer's tank.
The all-plastic pneumatic diaphragm pump can pump not only fluid liquids, but also transport some non-fluid media. Compared with self-priming pumps, submersible pumps, shielded motor pumps, clay slurry pumps and solids pumps, this model has many advantages.
The centrifugal chemical pump made of fluoroplastic type FSC (hereinafter referred to as the pump) developed by our company is a single-stage, single-pass cantilever centrifugal pump. It is manufactured using superior hydraulic design and advanced, proven processing technology.
Thanks to the reciprocating movement of the plunger, the working medium is directly sucked in or pumped out. Since the plunger and seal are in direct contact with the fluid, the correct choice of plunger material and seal type ensures more ideal pump performance during operation.
Equipment for water-chemical treatment, which is critical in the steam-water cycle of thermal power plants, industrial boilers, etc. Adding microdoses of ammonia water (NH₂OH) or liquid ammonia (NH₃) to the boiler feed water to increase the pH of the feed water (usually maintained in the range of 8.8–9.3 or depending on specific conditions) allows the formation of a stable protective film of magnetite (Fe₃O₄) on the surface of the metal (for example, carbon steel).
IJ type chemical process pump is a standardized chemical process pump upgraded and improved by our company based on IH pump. This pump adopts a single-stage, single-pass cantilever design, and its operating parameters comply with GB5662-85 standard (equivalent to ISO2858-1975).
Technical parameters: working depth under water up to 15 m, productivity up to 200 m³/h, pressure up to 24 bar.
The 3HS25 series high-pressure three-screw pump is designed for use in the machine tool industry and is suitable for pumping various cooling and lubricating materials (coolants, emulsions, cutting fluids, etc.) required for machine tool processing. Provides precise washing, cooling, lubrication, crushing and chip removal of workpieces and tools, extending tool life and improving machine precision.
Technical parameters: maximum capacity 400 m³/h, maximum pressure 24 bar
Equipment for automatic and precise dosing of chemical reagents into circulating cooling water systems, boiler plants or other water systems. Its main purpose is to prevent scale formation, corrosion and biological fouling (algae, bacteria) in the system by dosing certain chemicals, thereby ensuring its safe, stable and efficient operation.
Using the most advanced welding technology, KQDP/KQDQ has high corrosion resistance and high efficiency. Efficiency can be 5-10% higher than cast pumps.
A magnetic centrifugal pump (hereinafter referred to as a magnetic pump) usually consists of an electric motor, a magnetic coupling and a corrosion-resistant centrifugal pump. Its main feature is the use of a magnetic coupling to transmit power in a completely leak-free manner.
