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.
