Perhaps. The key is to know how many 'amps' your pump will draw. Check the specifications for your pump and see what that value is. That value should always be lower than the SSR amperage specified value that you choose, but not so close as to cause a surge upon start-up. We recommend a 25% 'window'. e.g. if you choose an SSR that is 10 Amps and your load draws 9 amps, a 10 amp SSR will do, but we suggest that you move up to the next amperage in size due to any 'start-up' surges that may occur.
