Description
Specifically designed for stationary diesel engines. When a switchgauge detects a dangerous condition in an engine, the mechanism is de-energised and pulls the fuel rack of the injection pump to a ‘stop’ or ‘no fuel’ position.
Murphy Rack Puller for Diesel Engines
The RP75 rack puller is a semi-automatic device that provides a pulling force to initiate shutdown of diesel engines and equipment.
The RP75 connects to the injection pump or air intake shut-off lever via a cable (chain optional). A coil spring, within the RP75, is reset manually and is held in place by an electromagnet. When the Swichgage® detects a malfunction, the electromagnetic circuit is interrupted through a Magnetic Switch–releasing the coil spring thus pulling the cable/chain to actuate shutdown. The spring, when fully compressed, exerts a pull of 30 lbf (133 N).
The RP75 is available for 12 or 24 VDC applications and is compatible with all Swichgage® instruments.
Features:
- Pulls injection pump or air intake shut-off lever
- 30 lbf (133 n) operating force
- Models available for 12 or 24 volt systems
- Operates on signal from Swichgage® installed on the engine or driven equipment
