The SHURflo 4048-153-E75 is a higher-flow 12V freshwater demand pump. Its manufacturer exploded view separates the pressure switch, upper housing, valve plate, diaphragm drive and motor, helping identify whether service requires a small component or the complete pump head.

The complete 4048-153-E75 water pump is shown separately from its repair parts. Pentair also lists valve assembly 94-800-01 and check valve 94-800-03 for this model, even though those part numbers are shared with other SHURflo series.

Choose the right part for your model
The 4048 High Flow is different from the Revolution 4008. Check the 4048-153-A75 (OEM) or 4048-153-E75 (aftermarket) model on the label. They share valve assembly 94-800-01 and check valve 94-800-03 with some other SHURflo pumps, but use their own 94-801-01 upper assembly, 94-801-05 pressure switch and 94-801-04 complete head kit.
The manufacturer's 4048 kit chart identifies 94-801-01 for upper housing, 94-800-01 for the valve assembly and 94-801-04 for the complete pump-head kit. Do not confuse the pump-head service kit with the complete pump sold with its 12V motor.
