GPS430 1-1/2”/38mm CSA-Certified FIT Metal Pump

The Wilden® FIT metal pump sets the new standard for pump performance. A reliable performer, this pump has superior flow compared to competitor CSA-certified pumps.

The FIT design uses a wetted path that minimizes the number of fasteners and allows for single socket reassembly for faster, easier maintenance compared to legacy Wilden pumps and competitors.

FIT pumps are designed for superior containment, ease of maintenance, and are a direct replacement for existing CSA-certified pumps in the field. All FIT CSA-certified pumps are constructed of approved materials and include a grounding cable, as well as a single point exhaust option to simplify the recapture of exhaust gases.

CSA (Canadian Standards Association)


CSA (Canadian Standards Association) test products for compliance to national and international standards, and issue certification marks for qualified products. Certification marks tell customers and users that a product has been evaluated by a formal process-involving examination, testing and follow-up inspection-and that it complies with applicable standards for safety and performance. The CSA certification document has been prepared, approved, and published by CSA International, and contains rules, requirements, or procedures for an orderly approach to a specific activity. CSA standards includes product design requirements, test methods, classifications, recommended practices, and other considerations. This certification is designed to meet many standards that define safety requirements intended to reduce the risk of personal injury.
