Due to the special reasons of high viscosity and high specific gravity of tomato sauce, the commonly used self-priming pump products are not competent for such conditions, so what kind of pump should be used to deliver tomato sauce? We suggest that you choose the following two types of pumps for reference:
1. If the need to move easily, it is recommended to choose pneumatic barrier pump, but it should be noted that tomato sauce belongs to food category. When choosing pneumatic barrier pump products, stainless steel pneumatic barrier pump should be used with food grade diaphragm. Pneumatic barrier pump products mainly rely on air source as power. The pump body is compact and bulky. If it is a pneumatic partition with 50-100 caliber, it can be used easily When the gap pump is easy to move, it is more suitable to match the corresponding trolley. Another feature of the pneumatic barrier pump is energy saving. When multiple pneumatic barrier pumps are working, one air compressor can be selected to drive it.
2. If the demand head is high, the outlet flow pressure demand is stable, it is more appropriate to choose screw pump products. Of course, the stainless steel screw pump made of stainless steel material should be selected as the same as the barrier pump, and the natural rubber sleeve of food grade should also be selected for the rubber sleeve. In addition, it should be noted that when selecting screw pump products as tomato sauce pump, the screw pump must be equipped with a set of reducer, and speed regulating screw pump products can also be used to reduce the speed of screw pump. The commonly used screw pump speed is 960r / min. when the screw pump is used for tomato sauce, the rotation speed should be controlled at 290r / min. after the speed is reduced, the flow of various screw pumps will be changed For example, the original product flow rate of g50-2 screw pump is 8m3 / h, while the flow rate after installing reducer is 5M3 / h-6m3 / h. After the reducer is installed, the rotation speed can be reduced to deliver high viscosity medium. Otherwise, the screw pump can not be used normally due to the selection problem.
