Standard Pitless Units - NSF 61 Certified
Brand: Baker Water Systems DivisionThe Monitor Standard Pitless Unit is a specialized piece of equipment manufactured specifically for the purpose of completing a Municipal / Industrial water well.
The Monitor Standard Industrial Pitless Unit attaches to the well casing and provides a sanitary underground discharge to the water treatment facility. The Standard Pitless Units are available for the following well diameters: 6”, 6.6”, 8”, 10”, 12”, 14”, and 16”.
The Standard Pitless Unit is manufactured using a cast spool and discharge Body. The spool and discharge body are galvanized using Lead-Free Zinc for long term corrosion protection.
Monitor Standard Pitless Units are shipped as complete factory pressure tested pitless unit including the Watertight Premium Well Cap, Upper Bury Depth Casing Extension, Discharge Body, Spool, Discharge and Drop Connection, Lift-Out Bail, and Hold-Down Assembly.
Monitor units conform to the Recommended Standards for Water Works, Great Lakes Upper Mississippi River Board of State Public Health & Environmental Managers, Water Systems Council and PAS-97 (04) Standards.
Monitor Standard Pitless Units are shipped as complete factory pressure tested pitless unit including: Watertight Premium Well Cap, Upper Bury Depth Casing Extension, Discharge Body, Spool, Discharge and Drop Connection, Lift-Out Bail, and Hold-Down Assembly.
Available options include Epoxy coating, API drop pipe and discharge threads, Cap cable seals, Locking seal caps, Flowing well spools, Flanged upper casing, Water sampler valves, Wire seals, Probe tubes, and Additional conduit entrance connections for signal wires.
Features- Corrosion Protection — all water passages are either hot-dipped lead free galvanized or constructed of corrosion resistant material
- Easy 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 and any possibility of dropping the inner assembly into the wall.
- Reliable Seal — Neoprene O-Rings between accurately machined hot-dipped lead free galvanized surfaces on the spool and within the unit provide positive seals.
- O–ring Seal Protection — Monitor seal protection prevents seal damage during installation and service.
- Frost Proof — No Heating is required
- Quick to Install — A quality pump installation can be made easily and economically without delay for masonry or building construction
- Alternative Spools — Spools are available plan (EO) or with silent check valves (E2-Double)
- Watertight Well Cap With Screened Air Vent — Designed to permit removal without disconnecting cables. Watertight cable and conduit sealing is optional
- Hold-Down — Supplied with each unit. Hold-down pipe also serves as lift-out pipe for installation and servicing.
- Reinforced O-ring Lands — Cast in to prevent discharge body from becoming out of round
- Depth Test Block — Standard on all units
- Options:
- Sealed Conduit Connection — Watertight conduit seals made of neoprene are available for most common cable sizes. (Round Wire Only)
- Epoxy Painting — Can be done, if required for extra protection in certain soil types
- Additional Tapping In Spool
- Transition Sleeve for Mechanical Joint Discharge
