EASY ACCESS TO SERVICE... Well cap can be removed without disconnecting cables. O-ring seals on spool permit withdrawal of the entire inner assembly simply by lifting. Replacement is equally simple. Spool support eliminates vertical adjustment allowing service above ground.

CORROSION PROTECTION... Spool and Discharge Body are either lead free hot-dipped galvanized or constructed of corrosion resistant material for longer life, less service.

RELIABLE SEAL... Neoprene O-rings between accurately machined lead free hot-dipped galvanized surfaces on the spool and within the unit provide positive seals to ensure maintenance free performance.

O-RING SEAL PROTECTION... Monitor seal protection prevents seal damage during installation and service eliminating potential service costs.

QUICK TO INSTALL... A quality booster pump installation can be made easily and economically without delay for masonry or building construction creating a sound cost savings solution.

ALTERNATIVE SPOOLS (6x7 and 8x10 only)... Spools are available plain or with silent check valves. The Monitor silent check valve has its operating parts automatically exposed when the spool is withdrawn. Spools are supplied with tappings for pressure controls.

WATERTIGHT WELL CAP... Designed to permit removal without disconnecting cables. Watertight cable and conduit sealing is available for additional protection.

HOLD DOWN... Supplied with each unit. Hold-down pipe also serves as lift-out pipe for installation and allowing speedy service.

FROST PROOF... No heating is required. All water passages are below the frost line.

ALTERNATIVE DISCHARGE & INLET CONNECTIONS... Are available to meet your requirements.
