Product Overview
The Grundfos 99725185 is an inline inlet filter for compatible SCALA1 booster-pump installations that draw water from sources where sand, grit, or suspended debris may be present. Installed on the suction side of the pump, the filter helps intercept larger particles before they enter the hydraulic components, reducing the chance that debris will restrict internal passages or interfere with pump operation.
The filter uses 1 in. connections with a female NPT inlet and male NPT outlet. Its confirmed filter rating is 250 microns with an identified 80% efficiency. Actual cleaning frequency depends on the source-water quality, flow demand, and amount of sediment present. This accessory does not replace source-water testing or additional treatment when the water contains fine sediment, dissolved minerals, biological contamination, or other conditions beyond its filtration rating.
