SCPD 56/26 DIN By-Pass
With two separate flows and a directly mounted By-Pass valve, the Sunfab’s SCPD 56/26 By-Pass DIN is the most flexible compact fixed flow pump on the market.
SCPD 56/26 DIN By-Pass is ideal for combination vehicles which require different flows and where there is a need to operate equipment while moving. The pump is primarily intended for engine-mounted power take-offs. The constant engagement is made possible by the By-Pass valve, which immediately relieves the load on the pump and power take-off when oil is not required. The pressure drop of the By-Pass valve is very low, so its function is energy efficient.
Product Benefits
The By-Pass valve can relieve the load from full operating pressure of 400 bar, which allows emergency stop function
The valve´s 24 V solenoids have integrated electrical cables which meet protection class ADR
