Sanitary Rotary Pumps Wholesale at Factory Direct

Our sanitary lobe pump mold mostly from one Ningbo factory which the boss was the engineer of Durrex company before, he is good at design and technical, but the sales ablity is just so so, we bought all of his mold after he finished his factory,even his factory was just established two years before,so we have one complete set mold for the sanitary lobe pump which from 0.55KW to 30 KW to fit your processing line market.

It’s also one of our biggest advantages, it can keep our pump quality modern and stable for you.

13 years manufacturing sanitary pump experience for dairy, food/ beverage, medicine/cosmetic, chemical.

No matter what style of sanitary rotary Pumps you want, based on our extensive experience, we can manufacture it.

Operating principle of lobe pump

Sanitary lobe Pump is also referred as colloid pump, rotary pump, three lobe pump, multi-purpose convering pump, and it may be categoried into positive dis-placemet pump.

By means of periodic conversion of several conveying units with constant capacity in working space,liquid conveying is realized theoretically.

Mechanical energy of primer motorwould be directly converted into pressure enrgy via pump, flow rate of the pumpis uniquely dependent upon volume variation of the working space and variation frequency within unit time,and is independent to outlet pressure.

In fact, material conveying in rotary pump is performed by a pair of rotors ins ynchronous rotation. Specific operating principe is showed as the schematic diagram of operating principle.

Rotor Lope Pump Structure Details

O-ring Configuration

O-Ring Material: The sealing rubbers we used are in compliance with hygienc and high purity requirements, such as FDA 177.2600, 3-A-18-03, Class II, USP Class VI Chapter 88 gb 4806 11 and so on.

There have four o-ring standard types for choose and scope of application

EPDM-standard
Tempeature -10℃ to 130℃. PH value about 5-9 which can tolerate with various media in the health field and industrial chemicals with low cost.

FKM(Viton)=option
Temperature -10℃ to 150℃ can tolerate various media in the health field, industrial chemicals, oils, and so on.

FFKM=option
Temperature -30℃ to 250℃ can tolerate various media in the health field, industrial chemical, oils, etc, can cover almost all media, higher cost.

HNBR=option
Temperature -10℃ to 150℃ can tolerate various media in the health field, industrial oils, etc, especially suitable for oil products.

Rotor Configurations

various rotor selection

Butterfly rotor ( recommended)

This type of rotor is our recommended style. Butterfly rotor is suitable for transporting material with particles with low particle breakage rate and small pulse.

3-leaves rotor (optional)

With particle breakage rate and smaller pulse than butterfly rotor, suitable for transporting all kinds of material.

Spiral 3-leaves rotor (optional)

With low particle breakage rate, very small pulse and high cost, suitable for transporting all kinds of material.

Single butterfly rotor (optional)

With a low particle breakage rate for large particles, large pulse, low pressure and small volume, suitable for transporting material with large particles.

2-leaves rotor (optional)

With partical breakage rate, large pulse, low pressure and small volume, suitable for transporting all kinds of material.

5-leaves rotor (optional)

With high particle breakage rate, very small pulse and smaller flow, suitable for transporting all kinds of material.
