What should you pay attention to when pumping food with gear pump
Double gear pumps often have problems such as easy leakage of seals, poor resistance to wear, poor self-priming, and short service life when conveying high-viscosity food media.Only reasonable selection of the material of the double gear pump; actively improving the processing technology of the double gear pump to better improve the processing accuracy of each part of the double gear pump and the assembly accuracy of the double gear pump can better meet the broad The actual needs of customers. The main issues of the double gear pump when conveying high viscosity food medium are: 1. The gears of the double gear pump cannot be nitridized, which will cause blackening of the conveyed food medium. 2. The shaft sleeve of the dual gear pump cannot use the steel back composite sleeve as usual. It should try to choose abrasion-resistant materials, such as silicon carbide or zirconia ceramics. 3. The sealing material of the dual gear pump cannot choose graphite filler medium. Food grade skeleton oil seals or double-end balanced alloy mechanical seals should be selected as far as possible to ensure food safety. 4. Double gear pumps should be equipped with gear reduction motors or variable frequency motors, stepless speed regulation motors, etc. when conveying high-viscosity food media.Minimize the use speed of the double gear pump.
