The K-type progressive cavity pump is a highly efficient and versatile fluid transfer equipment, adopting the K series gearbox, the length of the pump body is greatly shortened, which is especially suitable for the workplace with limited space. This not only reduces the difficulty of installation but also optimizes space utilization, saving valuable space resources for the user. k-type progressive cavity pumps are widely used in environmental protection, wastewater treatment, petrochemicals, food processing, pharmaceuticals, and other fields due to their strong self-priming ability, wide applicability, convenient flow adjustment, low noise and vibration, and resistance to high and low temperatures, etc., and are especially good in applications that require the conveyance of media containing solid particles or high viscosity media. Especially in the need to transport solid particles or high-viscosity media in the occasion of outstanding performance.
