PVD is an innovative technology that can deposit very fine and thin metal films on products. Applied to stainless steel sinks, this technology ensures the durability and longevity of the product's color and helps maintain its beauty. Nano-coating makes the sink antibacterial, waterproof and oil resistant. We also support custom handmade sinks, so sinks can be customized to the size and color you need.

Arc gear pump performance introduction
Circular arc gear pump because of the unique design of the structure, can be self-priming without the need for special self-priming device, but also because of axial transport axial flow rate is small and have a strong ability to suction or NPSHr value. Arc pump can also dry turn. Because moving parts do not touch each other during operation, a short dry run will not damage the pump components. This feature provides great convenience to the automated process, but dry running times are limited by a number of factors and are generally short . In addition, arc pump has no shearing and emulsifying effect during transportation, so it does not destroy the specific fluid properties formed in molecular chain structure and working process. Because the transmission relies on synchronous gear, the pump has low noise and little vibration , Work smoothly Arc pump can be divided into built-in bearings and external bearings in two forms. In the built-in bearing structure of the bearing lubrication by the transport. External bearing structure of the arc pump cavity with the bearing is separate. Because of this structure and the side clearance existing between the screws, it can deliver non-lubricative media. In addition, adjusting the synchronizing gear makes the screw non-contact while transmitting half of the output torque to the driven screw. As with all screw pumps, the external bearing arc pump also has a self-priming capability and most pump delivery elements themselves are double-suction symmetrically arranged to eliminate axial forces and also have a large suction height. These features arc pump it in the oil field chemical and marine industries has been widely used.
