screw pumpperformance advantages: 1) Good inhalation performance, goodself-priming ability; 2) The flow is continuous and uniform, thenoise is low, and the vibration is small; 3) High speed can be used because theinertial force of the rotating parts in the pump is low; 4) Wide pressure and flow range; 5) The structure is solid and easy toinstall and maintain; 6)Less sensitive to incoming gases and dirt than other rotary pumps.   2. Screw pump performanceshortcomings 1) The performance of the pump is sensitiveto changes in the viscosity of the liquid; 2) Screw pump processing and assembly requirements are high.   E-mail: diffulaustralia@qq.com Tel: +86 15067446433 Wechat: LD15067446433 WhatsApp: +86 15869127991 /+86 15067446433 /
