Tetra 37 Helm Pump
The hydraulic helm pumps of this series are designed to manoeuvre small/medium quantities of oil.
They are strong and complete of non-return valve, the body has a tank function.
Hydraulic transmitters with this cubic capacity are usually used on systems installed on small vessels with servo assisted systems.
These transmitters are also used for outboard steering systems.
We recommend a 320mm as minimum diameter of the wheel.
