Seal Types
Type F 550 S with mechanical seal or Type F 550 SB with stuffing box.

Available Drive Motors
Three-phase electric or compressed air motors. Three-phase motors of 0.75 or 1.1 kW, with a speed of 930 or 700 rpm. For high viscosity, pasty substances a motor of 1.1 kW is required with a recommended speed of 700 rpm for viscosities exceeding 50.000 mPas (cP), because of the low velocity of such products. A speed of 930 rpm may be used if the product is still flowing or if a follow-on plate would support the continuous flow of the product to the pump inlet.
For viscosities up to 25.000 mPas (cP) a motor of 0.75 kW and 930 rpm will be sufficient.
On compressed air motors of 0.5 to 1.8 kW, the speed may be controlled by a valve in the air supply line.
With higher viscosities delivery rate will be lower, depending on the velocity of the fluid.
Values ±10% at 930 rpm. Delivery rate depends on the velocity of the fluid.

Scope of Supply
A complete eccentric worm-drive pump consists of: drive motor, pump, stator and hose connection.
