The design selection depends amongst other:<br />
An additional selection criteria is the difference in pressure performance of the various types.<br />
• Frist am rotary lobe pumps FL, maximum total head 120 m (12 bar)<br />
• Frist am circumferential piston pump <strong>FK</strong>, maximum total head 200 m (20 bar)<br />
• Frist am circumferential piston pump <strong>FK</strong>L, maximum total head 250 m (25 bar)<br />
The Fristam circumferential piston pumps are manufactured with very close clearances. Thus<br />
they can generate a small vacuum in the suction pipeline. Due to the atmospheric pressure<br />
or system pressure the product is forced into the pump chambers.
