Flexible rotor pump (HDRB) is widely used as a substitute for various types of pumps. It has strong self-priming, large flow, small size, low cost performance, and is known as an energy-saving pump.
Product performance:
1. Strong self-priming force, perfect structural principle, dry self-priming 6 meters, with material self-priming **** 9 meters
2. Short self-priming time, instant self-priming within 6 meters, completed in 2-3 seconds.
3. Simple structure, easy maintenance, no need for professional guidance, and no need to dismantle the pump pipeline for maintenance.
4. Buy a pump once and use it for life, with few wearing parts.
5. Small size and takes up little space for on-site equipment.
6. High efficiency with large flow, low power and more energy-saving under the same flow.
7. Noise-free indoor installation
8. It can transport hard particles containing granular impurities.
9. The viscosity of the conveying medium can reach 5000 centipoise
How it works
① There is an eccentric block in the pump chamber. When the flexible blades leave the eccentric block, the volume between the blades continues to increase, creating a vacuum, which allows the liquid to be continuously sucked into the inlet of the pump chamber.
② When the flexible blades rotate, the liquid is brought from the suction part of the pump chamber to the discharge part.
③ When the flexible blade contacts the eccentric bump again, it bends and is accompanied by a squeezing action, so that the liquid is discharged from the pump chamber uninterruptedly and without pulsation, thus completing the whole process of suction and discharge.
As the core technology of flexible pump , the impeller of the pump should have good elasticity, small deformation, and be able to withstand long-term high-frequency flexion without breaking or tearing. "Ten years of hard work", the excellent impeller elastomer technology determines the excellent performance and durability of the pump. There are two types of impeller materials: sanitary nitrile rubber and EPDM rubber; nitrile impellers are mainly used for vegetable oils, mineral oils, oil-containing media and areas with high hygiene requirements; EPDM impellers are mainly used for a wide range of media such as weak inorganic acids, organic acids, alkalis, salts, alcohols, ketones, sewage, etc.
Features:
Small size, large flow rate - Generally speaking, compared with competitive pumps, the volume is smaller at the same flow rate. Easy to install and move.
Instantaneous and completely self-priming - no additional equipment is required, and no liquid replenishment is required before starting. The suction range can reach up to five meters.
The pump body is made of stainless steel precision casting, and all the metal parts passing through the flow are made of stainless steel (1Cr18Ni9Ti).
The viscosity of the conveying medium can reach 2000 centipoise
Can transport gas-containing liquid and foam liquid without air blockage
It can transport media containing suspended soft and hard particles.
The gentle action of the rotor does not damage shear-sensitive media, such as papermaking dispersants.
The flexible rotor has no metal contact and does not generate sparks when in operation; it is especially suitable for conveying solvents such as alcohol, gasoline, and water when equipped with an explosion-proof motor.
Beautiful appearance, durable and easy maintenance
application:
The excellent self-priming performance and strong adaptability to working conditions of this pump make it suitable for various industrial occasions, such as emptying barrels, cleaning warehouses, sucking and discharging liquids in underground tanks, sampling, and conveying various fluids and semi-fluids. For example, when emptying barrels, you only need to insert the inlet hose into the barrel to suck and drain. It widely replaces centrifugal self-priming pumps, submersible pumps, gear pumps, single screw pumps and other pumps.
Chemical industry - weak inorganic acid, organic acid, alkali, salt, oil, alcohol, ketone, ester and other wide range of media
