DPR series hot and cold water circulation pipeline pump

Product Introduction
Dayuan Pump Industry's DPR series of hot and cold water circulation pipeline pumps is a new generation of products designed based on our company's many years of production experience. The design of this series of products optimizes the hydraulic design through CFD fluid simulation analysis technology, and the hydraulic efficiency is higher. The mechanical seal uses high-temperature resistant rubber to improve the high-temperature resistance of the mechanical seal and reduce the aging rate. The "O"-shaped sealing ring is made of EPDM material, which improves the service life of the seal as a whole.

Features

1. Ultra-wide voltage operating range 180v-240v 2. Impeller 304 stainless steel, stainless steel welded shaft, electrophoretic coating process for flow-through parts 3. Bearing high-temperature grease, mechanical seal high-temperature resistant material 4. High efficiency, good energy-saving effect 5. Protection level, up to IP55
