The cam-type double rotor pump is a high-tech and top-notch fluid delivery equipment imported and developed by LAFA from Sweden, and it is a multi-functional new rotor pump manufactured with advanced technology. The professional manufacturing technology and manufacturing precision of the products fully meet the international level.
This product uses two synchronous rotors, the rotors are driven by a pair of synchronous gears in the box, and the rotors are driven by the main and auxiliary shafts to rotate synchronously in the opposite direction to make the pump The inner cavity of the pump is changed, thus forming a higher vacuum degree and discharge pressure, which is more suitable for the transportation of sanitary grades and corrosive high-viscosity media.
The manufacturing standards of this product are divided into five series: food grade, common type, special type, chemical type, and oil type. In terms of structure, it can be divided into two categories: high pressure and high viscosity, high pressure and low viscosity.
With the superior performance of the cam-type double-rotor pump, it can replace more commonly used centrifugal pumps, single-screw pumps, twin-screw pumps, etc.

凸轮式转子泵批发时选用油浴润滑系统，假如油温在60℃（140°f）下列，而且润滑油没有被污染，那么一年更换一次润滑油即可。假如油温在60-100℃(140-210°f)，那么一年内要换四次润滑油。假如油温为100-120℃(210-250°f)，就需要每月更换一次润滑油。假如油温高于120℃(250°f)，就需要每周更换一次润滑油。
正确的安装和维护是轴承正常运行的关键因素，同时，应该注意维持泵轴承的洁净度。轴承务必防止污染和湿冷，而且必须正确安装和润化。此外，轴承柱的设计、油封的状态、润滑液的方式、更换周期和特殊维护也起到重要作用，都必须引起关注。
零件膨胀：高温下，金属零件会以不同的速度膨胀。在国产凸轮式双转子泵的挑选环节中，这一点尤其重要，并会对你选择的结构材料。
保温或维持低温：在一些前提下，你的运用可能需要保持一定的温度。这能通过维持流动标准或使用保温筒夹/总体保温来达到。
