Additional equipment is sometimes needed to keep an extrusion or finishing pump primed. Follower plates, lifts and rams assist the flow of material into the pump inlet. Lifts can be used for fluids with viscosities up to 200,000 cPs. Rams are needed for fluids with higher viscosities. If a fluid is stringy, a ram may be needed for fluids with viscosities as low as 60,000 cPs. Carts allow for mobility when engaging in finishing applications where pump location counts.
