Abstract
In a screw displacement pump for non-lubricating fluids, especially aviation spirit, the pump body is made of a thermosetting plastic or metal coated with the plastic, and the rotors are made of metal or vice versa. The plastic may be a phenol-formaldehyde condensate and may be of the fabric laminated type.
