It won't harm pump life the main concern would be that as a sump return this would cause water level variations and potential havoc with skimmers and ATO's. The 1073.050 made before mid 2015 that lacks a 7090 controller will work with no mods, the newer ones include a stripped down 7090 that lacks a DIN port and lets you just set one fixed speed, to connect it to an Apex you need to replace the controller with the 7090.500.
