ZB-R rubber gear pump
Rubber gear pump(ZB-R) is also named as extrusion melt pump or gear pump for rubber, and has the function of automatic cleaning efficiency, simple design, optimization of the fluid channel. Pulse rate is lower under high pressure differential.

Rubber gear pump   gear pump for rubber

Gear pump for rubber applications:
ZB-R series rubber melt pump is efficiently self-cleaning. The structure for shaft sleeves is simple, while the fluid passageway is specially designed. All of this make the pulsation rate become much lower under the higher differential pressure. This series of melt pump applies to butadiene rubber, chloroprene rubber, EPDM, SBR, NBR, natural rubber, etc.

Rubber gear pump ZB-R technical parameter:
Material for Melt Pump Body: High temperature tool steel or chromenickle steel
Material for Gear: High temperature tool steel or nitrided steel
Material for Sliding Bearing: High temperature tool steel, special materials or coating
Shaft Sealing: Spiral Discharging
Heating System: Heating medium heating
Cooling System: Shaft end cooling
Model/Volume Range: 50CC - 2500CC, 50cm3/rev - 2500cm3/rev

ZB-R gear pump for rubber operating parameter:
Mooney ML1+4(100): to 120
Working Temperature: ≤130℃
Cleaning Temperature:≤350℃
Inlet Pressure: ≤70MPa
Differential Pressure: ≤50MPa

Rubber gear pump(ZB-R) applications and properties:
Rubber gear pump ZB-R series extrusion melt pump has the function of automatic cleaning efficiency, simple design, optimization of the fluid channel. Pulse rate is lower under high pressure differential. Melt pumps for extrusion are suitable for butadiene rubber, chloroprene rubber, EPDM, SBR, NBR, etc. in the process of natural rubber.
At present in the rubber industry in China has been plagued by extrusion production enterprises, we have the very high viscosity of rubber production, strict temperature control, generally only a few dozen degree high, easy to cure, the barrel inner import and cold water circulation, the practice after the cut direct feed extruder, extruder shear force by conveying to die, due to artificial feeding, and the strip size is not uniform, resulting in pressure is not stable, directly affect the product quality of tolerance, there is no way to guarantee that.

Batte company is the first successful development of extrusion gear pump manufacturer, product use and verified, the indicators are in line with the requirements of the production process, to the use of manufacturers to bring revolutionary spring quality.

Advantage of gear pump for rubber:
1, stable output pressure
2, improve the quality of products
3, improve the productivity of extrusion
4, reduce unit energy consumption
5, to extend the service life of the whole machine
