Customer's Needs and Problems

A curing agent is added to sand during the process to create the sand mold for cast metal production.
A gear pump was used to supply the curing agent, controlling the amount to inject with a solenoid valve, which posed the following problem.

  • Curing agent leaking from the shaft seal of the pump solidifies and adheres to the pump when exposed to air, leading to pump malfunctions.

TACMINA's Solutions

The gear pump was replaced with a Smoothflow Pump.

  • The completely sealed structure does not have a shaft seal, so the curing agent is never exposed to air.
