Opti Line ACG8 Screw pump Product description Flow volume: 80]1200 l/min Max differential pressure: 16 bar Applications: Lubrication, circulation and transfer OACG8 1101.01 GB

OACG8 1101.01 GB 2 www.imo.se Design The Opti Line ACG pump is a positive displacement pump of 3-screw type. The design basically meets the requirements of EN ISO 14849. Pressure relief valve The pump is equipped with an integral pressure relief valve with internal return, limiting the differential pressure across the pump and protecting the pump, should the discharge line be blocked. The valve is adjustable for different opening pressures. The value of the pressure limit can be set at the factory and should be adjusted at in stal la tion (see Installation & Startup instruction for low-pressure...

www.imo.se 3 Speed The maximum speed is 3600 rpm. For higher speeds contact your IMO representative. Rotation The ACG pump is designed to operate in one rotational direction only, as standard clockwise when facing the shaft end. For shorter periods of time, a few minutes for emptying a discharge line, the pump may be operated in reverse direction, provided the back pressure is limited to 3 bar. Fluid viscosity 1.6 cSt up to 1500 cSt. Fluid temperature ]20°C up to 180°C.
