详情描述

The melt pump at the bottom is primarily used for high-pressure conveying of high-temperature, high-viscosity media in vacuum reactors, featuring an oversized suction inlet design that can be directly connected to the bottom of the reactor.EvenUnder vacuum conditions, high-viscosity materials can be effectively吸入 into the melt pump, featuring high self-priming capability and high output pressure.

Installation Method

During equipment installation, the inlet flange of the bottom pump is directly connected to the outlet of the reactor bottom. The gear pump is connected to the driving motor via a universal joint, which drives the gear pump to rotate. The bottom pump does not share a base with the motor and gear pump during installation, so the customer needs to fix the transmission motor themselves as required.
