Floats Switches and Assemblies

Orenco^® Signal-Rated (Non-Mercury) Float Switches are used with pump control panels and alarms in areas where components containing mercury are prohibited. They’re intended for low-amperage signals and aren’t capable of carrying the current necessary to start or operate a pump. They have a “drawdown” value — the difference in liquid level between the switch’s activation and deactivation points.

“N” Model

• Normally closed default state (contact is open when float switch is floating)
• Approved for intrinsically safe relays (very low amperage)
• Suitable for electromechanical panels with “RO” option
• 2-inch (51-mm) drawdown
• Super Vu-Tron® cords: flexible 2-conductor (UL, CSA) SJOOW

“P” Model

• Normally open default state (contact is open when float switch is hanging)
• Approved for intrinsically safe relays (very low amperage)
• Suitable for Orenco MVP and VCOM panels
• 2-inch (51-mm) drawdown
• Super Vu-Tron® cords: flexible 2-conductor (UL, CSA) SJOOW

Orenco^® Discharge Assemblies are used to transport effluent from a pump to a location or component that is downstream in the treatment train. High-head and low-head configurations are available, as well as a drainback feature that can be included with high-head or low-head discharge assemblies.

• Corrosion-resistant
• Solvent-welded or threaded and sealed connections
• Simple to install and maintain
• Optional cam-style quick-disconnect fittings
• Flexible hose to dampen pump vibrations and simplify installation and maintenance
• Drainback feature for shallowly buried tanks and transport lines in cold climates
• 1-inch, 1¼-inch, 1½-inch, and 2-inch nominal diameter piping available (25-mm, 32-mm, 40-mm, and 50-mm DN)
• High-pressure
• Cold-weather kits available

Orenco^® Cold-Weather Kits for discharge assemblies are coupled with a high-head discharge assembly for use with deeply buried tank and transport lines in cold weather.

• Designed for use with Orenco high-head discharge assemblies
• 1-inch, 1¼-inch, 1½-inch, and 2-inch nominal diameter kits available (25-mm, 32-mm, 40-mm, and 50-mm DN)
• Models with 1⁄8-inch drain hole or no drain hole available

Orenco^® Motor-Rated (Non-Mercury) Mechanical Float Switches are used with pump control panels and alarms in areas where components containing mercury are prohibited. They are intended to carry starting and operating current for a pump. They have a “drawdown” value — the difference in liquid level between a float switch’s activation and deactivation points. The default state is normally-open (contact is open when float switch is hanging).

“B” Model

• Normally open default state (contact is open when float switch is hanging)
• Ideal for areas where components containing mercury are prohibited
• ½-hp (0.37-kW), 120-VAC switch power or 1-hp (0.75-kW), 240-VAC switch power
• 13 Amps (120-VAC and 240-VAC switches)
• 4.00-inch to 4.75-inch drawdown (101-mm to 121-mm)

“C” Model

• Normally open default state (contact is open when float switch is hanging)
• Ideal for areas where components containing mercury are prohibited
• Suitable for use with potable water
• ½-hp (0.37-kW), 120-VAC switch power or 2-hp (1.49-kW), 240- VAC switch power
• 13 Amps (120-VAC switch)
• 15 Amps (240-VAC switches)
• 5.50-inch to 9.50-inch drawdown (140-mm to 241-mm)

Orenco^® Float Switch Collars are the simplest, most reliable way to attach a float switch to a Schedule 40 PVC float switch stem.

• Secure, non-slip attachment for float switches
• Models for 1-inch to 3-inch (25-mm to 75-mm) Schedule 40 PVC float switch stems
• Durable ABS construction
• No special tools required for mounting or adjusting
• Quick-release clip
• Works with 18/2 and 16/2 AWG cords (MFCOLLAR1) or 16/3 AWG cords (MFCOLLAR1L)

Orenco^® Flex Extensions are recommended for installations where tank settling may occur, to avoid line breakage during settling.

• PVC flex hose extension
• 1-inch, 1¼-inch, 1½-inch, and 2-inch nominal diameters for discharge available (25-mm, 32-mm, 40-mm, and 50-mm DN)

Orenco^® Float Switch Assemblies are preassembled with one or more floats secured by float collars mounted on a 1-inch (25-mm) PVC float stem.

• Preassembled
• Easy to adjust in the field with no special tools
• Quick-release clips

Orenco^® Float Brackets are installed on the inside of a PVC access riser for mounting a float stem and float switches. Two models are available.

• PBFB model adhesive-mounts close to riser wall
• RRFB model bolts into riser wall for offset mount so stem aligns to tank opening
• Accepts 1-inch NPS (25-mm DN) float switch stem
• Ideal for system upgrades and repairs
