Currently, there are three major types of metering pumps available on the market: screw pumps, gear pumps, and piston pumps.
Among all metering pumps, screw pumps exhibit the best durability. Ceramic screw pumps are approximately 10 times more wear-resistant than ordinary screw pumps. Currently, screw pumps are predominantly used to control the dispensing of high thermal conductivity resins on the market.
The screw valve has the characteristics of stable medium delivery, low turbulence of the discharged medium, weak pressure pulsation, small mechanical vibration, low noise, self-priming performance, good suction performance, high speed working ability, insensitive to the viscosity of the medium, simple and compact structure, small size, light weight, high efficiency, reliable operation, long service life, convenient operation and maintenance, etc.
Hedaray screw valve is easy to be integrated with mechanical equipment. The screw valve makes the medium delivery smooth, uninterrupted and pulse-free, prevents dripping and effectively prevents the phenomenon of wiredrawing and dripping of the medium.
Be able to convey media containing particles or fibers with particle diameter of 30 mm (not exceeding the eccentricity of the rotor). The fiber length is 350 mm (equivalent to the pitch of a 0.4 rotor). Its content can generally reach 40% of the medium, if the solid in the medium is fine powder, the content can be as high as 60% or higher, and it can be transported smoothly.
Hedaray screw valve has high wear resistance and high stability, the company's main products are screw valves, screw pumps, ceramic screw pumps, welcome new and old customers to do free screw valve test!
