Stainless steel gear pump is a gear pump that is widely used and has acid and wear resistance. The pump valve equipment is mainly used in small flow, high-lift water systems, such as drinking water supply systems, pressure boiler water supply systems, high-purity water purification systems, and washing and spraying processes in industries such as medicine, food, fine chemicals, and papermaking.
This kind of stainless steel gear pump often has problems such as easy leakage of the seal, poor wear resistance, poor self-priming, and short service life when transporting high-viscosity food-based media. Only by choosing the material of the stainless steel gear pump reasonably, actively improving the processing technology of the stainless steel gear pump, and improving the processing precision and assembly precision of each part of the stainless steel gear pump, can we meet the actual needs of our customers.
Next, I will explain in detail the matters needing attention when the stainless steel gear pump transports high-viscosity food media:
1. The stainless steel gear pump gear cannot be nitridated, which will mainly cause the food medium to be transported to become black.
2. The shaft sleeves of stainless steel gear pumps cannot use steel back composite sleeves like conventional ones. Try to choose wear-resistant materials, such as silicon carbide or zirconia ceramics.
3. The sealing material of stainless steel gear pump cannot choose graphite packing medium. It is necessary to choose skeleton oil seal or double-end balanced alloy mechanical seal to ensure the safety of food.
4. The stainless steel gear pump should be matched with gear reducer motor or variable frequency motor, stepless speed regulating motor, etc. when transporting high viscosity food medium. Try to reduce the operating speed of the stainless steel gear pump.
Therefore, when choosing stainless steel gear pumps, we should choose carefully, don't blindly, don't be greedy for cheap, and pay attention to materials. Our company specializes in the production of various stainless steel gear pumps, KCB stainless steel gear pumps, YCB arc stainless steel gear pumps, magnetic drive stainless steel gear pumps, etc. The stainless steel gear pump suitable for your working conditions can be customized according to the different needs of customers.
