Energy saving and high efficiency
Efficiency can reach MEI ≥ 0.7
Safe and secure
With the same flow and pressure, the height is lower, the vibration is lower, the noise is lower.
High quality
Using the most advanced welding technology, KQDP/KQDQ has high corrosion resistance and high efficiency. Efficiency can be 5-10% higher than cast pumps.
Highly efficient engine
Fully enclosed, external fan, squirrel cage, highly efficient three-phase asynchronous motor, its efficiency is 2-10% higher than conventional motor.
Standards
GB/T 5657-2013
Applications
Models KQDP/KQDQ are multistage vertical booster pumps. Their main advantages are energy saving, environmental protection, safety and reliability. They can pump various types of liquids and are used in water supply systems, industrial pressure boosting, industrial liquid pumping, circulation in air conditioning systems, irrigation, etc. KQDP can be used in environments with non-corrosive liquids, KQDQ - in environments with slightly corrosive liquids.

This series of horizontal centrifugal pumps are horizontal, radial split, open back, single stage, single suction volute type centrifugal pumps. The design of the impeller is closed type. The pump body has an axial suction pipe, a discharge pipe located on top, and a foot support.
DN15–DN1800; PN10–PN320, Class150–Class1500; carbon steel, stainless steel, cast iron; flange, thread, welding; rotary, lifting, disk types.
CAD technology is used to redesign the design multiple times to ensure that the submersible pump body and impeller are perfectly matched, allowing fibers and debris to pass through easily without becoming tangled or clogged.
Although reagent dosing plants in the petroleum and petrochemical industries do not directly produce products, they are an indispensable “guardian” and “lubricant” in the entire production chain.
The simple modular dosing unit is a complete plug-and-play dosing device. It is designed, manufactured, assembled and tested at the manufacturing plant in accordance with the customer's technological requirements, and then completely delivered to the site.
DN25–DN1200; PN16–PN160, Class150–Class900; cryogenic steel LF3, stainless steel; t=-196℃…+120℃, extended rod, flanged and welded connection.
The static seal between the suction section, middle section and discharge section of the pump is made of metal seal and double O-ring seal, and the pump shaft seal uses high-performance hemp packing or mechanical seal, which is safe and reliable.
The DG series segmental multistage centrifugal pumps use tension pins to connect the suction section, intermediate sections and discharge section into a single unit.
Regular stock of frequently used spare parts and wear parts to ensure timely delivery in case of urgent need.
DN50–DN2600; PN10–PN63, Class150; cryogenic stainless steel body, special seal for low temperatures; t=-196℃…+60℃, extended rod, wafer and flange versions.
Can pump clean water and slightly contaminated water with temperatures up to 40°C and pH 4–10; the maximum diameter of passing particles is 100 mm.
Technical parameters: capacity up to 100 m³/h, pressure up to 48 bar
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.
Equipment for water-chemical treatment, which is critical in the steam-water cycle of thermal power plants, industrial boilers, etc. Adding microdoses of hydrazine solution to the boiler feedwater reacts chemically with the dissolved oxygen (O₂) in the feedwater to form nitrogen and water.
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.
