Pumps for polyurethane

Wanner International has introduced a range of Hydra-Cell multiple diaphragm pumps to meet the specific needs of polyurethane production.

The Hydra-Cell multi-diaphragm pump has no dynamic seals and handles abrasive particles with ease, reducing maintenance costs.

Wanner says that with new PTFE diaphragms, chemical compatibility and service life are no longer concerns. Hydra-Cell pumps with these diaphragms have been tested extensively and shown to be able to operate reliably at full flow under flooded suction conditions.

Meeting the performance standards of API 675, the pumps are accurate and repeatable, suitable for dosing and injection duties.

Completely contained, they provide no leak paths for potentially harmful chemicals and their multi diaphragm design ensures low shear, low pulsation delivery. The service life of the PTFE diaphragm is reported to be extended to 240 million cycles; 4000h @ 1000 rpm.
