Blue Defender Cam Rotor Pump

Working principle of cam rotor pump: the synchronous rotating rotor is adopted to rotate in the synchronous reverse direction under the driving of the main and auxiliary shafts, and the volume of the pump changes periodically.

There is no gap designed between the rubber coated three-blade spiral rotor and the pump casing. In the pump operation, the vacuum degree can reach 0.084, and the strong self-priming capacity can be realized without pump priming.

The manufacturing process of Blue Defender cam rotor pump complies with the requirements of Standard API676, the dry installation mode is adopted, the core technology is the three-blade spiral full-rubber-coated rotor, which is wear-resistant, non-blocking, and suitable for conveying high-viscosity and particulate-containing media.

According to the working principle of Blue Defender cam rotor pump, we provide a variety of import and export flange types, such as standard straight flange, S-type flange, 90-degree flange, which can be customized according to the application conditions.

According to the working principle of Blue Defender cam rotor pump, independent reducer is required, which has the advantages of wide speed ratio range, large torque, stable in service and small noise.

 

Product classification: cam rotor pump

1.Full-rubber-coated rotor, with wear and corrosion resistance

2.The three forms of gas, liquid and solid can be subject to mixed transportation, allowing dry running

3.Its self-priming height is 8 m, no water diversion is required

4.Forward and reverse rotation, suction when rotating forward, and high pressure flushing when rotating reversely

5.Quick-opening pump cover, online replacement of accessories, short axial size, and small maintenance space

6.High viscosity (10,000 CP), large flow (0.1-2,000 m³/h)

 

 

Technical parameters

 

Flow: 1 m³/h – 2,000 m³/h

Outlet pressure: 0.1 – 1.2 Mpa (single support);

Self-priming height: 0.1 – 8.7 m

Transport viscosity: 0 – 100,000 cp;

Diameter of particle passed through: 70 mm

Characteristics

1. Nitrogen treated pump casing

After the nitrogen treatment, the wear resistance, fatigue resistance, corrosion resistance and high temperature resistance of the nodular cast iron pump casing can be fully improved, among which the wear resistance can be improved by more than 3 times.

In addition to ductile iron pump casings, Qingdao Blue Defender Environmental Protection Co., Ltd. offers a wide range of pump casings in 304, 316 and 316L size.

2.Full-rubber-coated rotor

Rubber material: fluorine rubber (FPM), nitrile rubber (NBR), ethylene-propylene-diene monomer rubber (EPDM), hydrogenated nitrile rubber (HNBR)

Characteristics: oil resistance, wear resistance, corrosion resistance, especially suitable for transporting high viscosity complex media containing soft particles.

 

3.Cartridge mechanical seal/flushing system

Lubricate and cool the separate isolation chamber; select the seal ring of corresponding material according to the operating parameters, so as to achieve no leakage, corrosion-resistant requirements;

The lubricating oil not only lubricates the mechanical seal, but also plays the role of monitoring.

 

4.Low shear and low emulsification

It is beneficial to the treatment of oily sewage in oil field, to the protection the medium integrity, and to the treatment of next process.

5.Strong self-priming (S-type gooseneck flanges are use at the inlet and outlet)

No pump priming is required, self-priming without cutoff can be achieved when starting the machine, mixed transport of gas, liquid and solid can be achieved, and the self-priming height can be up to 8.5 m.

6.Forward and reverse rotation

It transports medium when rotating forward and flushes when rotating reversely, one pump for dual purposes, and is suitable for MBR membrane treatment, production water pump, oil depot unloading and emergency oil unloading pump.

7.Independent reducer

The Blue Defender cam rotor pump is fitted with independent reducer, which has the features of rich speed ratio, equipped with 4-stage motor, energy-saving, low noise and stable performance.

 

Requirements for type selection

 

1. Solid content

The higher the solid content, the lower the rotation speed of the cam rotor pump; in order to reduce the wear and prolong the service life of the pump, the small flow technology sometimes corresponds to the pump model with larger pipe diameter.

 

2.Viscosity.

The higher the viscosity, the lower the corresponding rotation speed; too high rotation speed will lead to operation cavitation, vibration and noise, and reduce the service life of the rotor and other accessories

3.The cam rotor pump is not sensitive to the impurities such as soft particles, long floc, fiber and plastic bag, and is characterized by no clogging and no winding.

 

Applications

The Blue Defender cam rotor pump is suitable for conveying corrosive and abrasive media, can perform mixed transport of gas, liquid and solid, and is insensitive to high viscosity media.
