YHCB circular arc gear pump is a kind of high efficiency and energy saving gear pump to meet the needs of industrial oil pump. The gear adopts double circular arc sine curve tooth shape structure, and the gear material can be selected according to the needs of nylon and 45# steel. It has the characteristics of high efficiency, low noise and long service life. Suitable for conveying viscosity in 5-1500cst, the temperature does not exceed 80℃, such as gasoline, kerosene, diesel mechanical lubricating oil diamine acetate, triamine acetate and hexamine acetate and other solid particles non-corrosive liquids is the ideal pump for the tank car modification industry and the petroleum sector.
Pump body: the inlet of the pump body has an increased negative pressure chamber, which improves the self-priming capacity of the pump.
Sealing: the form is skeleton oil seal, the material is chlorinated polyether plastic corrosion resistance.
Bearing: graphite bearing, self-lubricating material, chemical stability, corrosion resistance, can be applied to poor lubricity of the medium.
Shaft: the material is 40Cr, hard chromium plating on the shoulder of the shaft, improve the corrosion resistance of the part, reduce the surface roughness and friction coefficient.
Gear: material selection of nylon 1010 or copper gear, gear friction, collision does not produce sparks, can prevent ignition of flammable media.
