Open the CIPO recordAbstract From the Canadian patent
A multi-pump horizontal pumping system has a support structure with a plurality of pumps horizontally connected thereto in parallel and side-by-side relationship. A gear box operatively interconnects an electric motor to each of the pumps with a thrust bearing operatively connected to each pump shaft of each pump between the gear box and each pump. Piping conveys fluids to and from the pumps in parallel or series flow. The multi-pump arrangement provides redundant pumping ability in remote locations where pumps fail more often than the electric motors and in remote locations where size, and weight considerations prevent the use of multiple single-pump horizontal pumping systems.

Why it's free to use
- Filed May 6, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 6, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 6, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
