What should be paid attention to when stainless steel gear pump is used to convey food

Publish: Browse:
Stainless steel gear pump is referred to as stainless steel pump. When conveying high-viscosity food-like media, seals often leak, gears are not resistant to wear, poor self-priming, and short life. Only reasonable selection of the material of the double gear pump; actively improving the processing technology of the stainless steel gear pump to better improve the processing accuracy of each component of the double gear pump and the assembly accuracy of the stainless steel gear pump can better meet the needs of our customers Actual demand.
The main issues of the double gear pump when conveying high viscosity food medium are:
First, the gears of the dual gear pumps cannot be nitridized, which will mainly cause blackening of the conveyed food medium.
Second, the shaft sleeve of the stainless steel gear pump can not use the steel back composite sleeve as usual. It should try to choose abrasion-resistant materials, such as silicon carbide or zirconia ceramics.
Third, the sealing material of the dual gear pump can not 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.
Fourth, stainless steel 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 stainless steel gear pump.
