Sound protection for gear pump
Sound protection for gear pump
(OP)
We are using a gear pump in a research Lap in order to pump thermal oil for a test rig with different rotational speeds.
At high gear speed the sound of the pump motor is quiet loud.
Does anyone know companies which offer sound protections (probably pump encapsulations) in order to reduce the loudness of the pump?
Or is it advisable to design a kind of contaiment ourself. There are probably major implications with respect of cooling air flow for the motor?

RE: Sound protection for gear pump
You will have to mount the motor/pump combination on vibration isolators to reduce vibration transmission to the pump support structure.
Connect hose instead of hard plumbing to the pump to reduce vibration transmission to the circuit.
Very little heat transfer occurs from the pump to the air, that should not be a concern. If you have the pump directly driven by an electric motor, cooling the motor would be a concern.

Just a comment. We use a flexible corrugated SS metal hose to connect from the gear pump to the rest of the tubing. We can not use normal hose due to the fact that we have got up to 15 bar pump pressure.
I will have a look whether decoupling is possible. But the pump gear housing assembly looks quiet compact I am not sure whether it is possible to decouple it?

I would not be surprised to find that this will be less costly than trying to silence your noisy pump.
