CLOSE-COUPLED OPTION FOR 3-SERIES & H-SERIES

	Description
	Mis-aligned pumps add excess radial loads and stresses to shafts, bearings, and seals. This is one of the most common causes of premature pump failure. Liquiflo's Close-Coupled option was designed to eliminate the need of having to manually align the pump and motor.	Close-Coupled Additional Information (download PDF)
	Using our Close-Coupled option you simply bolt the pump and motor together and exact alignment is guaranteed. Pumps with the Close-Coupled option use the same repair parts and are just as easy to rebuild as our standard models. Pump maintenance and installation is further simplified since manual pump and motor alignment is no longer required.	Close-Coupled Additional Information (download PDF)

RANGE OF SEALS AVAILABLE
Liquiflo's universal front housings will accommodate packing, as well as single and double mechanical seal configurations.

Packing is suitable and the most economical for safe, non-hazardous liquids.

Single Mechanical Seals are used when leakage needs to be minimized. Single seals have a viscosity limit of approximately 5,000 cps and temperature limit of 500 °F.

Double Mechanical Seals require a flushing system and are typically used when pumping liquids that are abrasive, crystallize on contact with air, or are very dangerous.

External Mechanical Seals are used to isolate the seal body from the liquid being pumped or when pumping liquid under vacuum conditions.

OPTIONS FOR 3-SERIES & H-SERIES SEALED & MAG-DRIVE

	SANITARY FITTINGS Sanitary Fittings are available for food & drug applications
	RAISED-FACE FLANGES ANSI, DIN, JIS Flanges are available.
	CLAMP-ON TEMPERATURE CONTROL JACKET Temperature Control Jackets can maintain the pump at either elevated or reduced temperatures. Commonly used when pumping liquids that solidify or become difficult to pump when temperature decreases.

	DOUBLE WALL CONTAINMENT CAN Liquiflo's patented Dual-Kan controls the temperature of the back end of a magnetically-driven pump by circulating a heating or cooling fluid through the containment can for hot or cold applications. The Dual-Kan will compensate for increases in temperature due to eddy current losses from the mag-drive coupling.

RELIEF VALVE FOR 3-SERIES, H-SERIES, 2-SERIES, 4-SERIES SEALED & MAG-DRIVE

Every Pump Needs Relief
Positive displacement pumps should be installed with a relief valve in the discharge line. This will protect the pump and piping should a valve be closed inadvertently. Liquiflo manufactures two sizes of relief valves in both 316-SS and Alloy-C for this purpose.

Why Use Mag-Drives?
Magnetically coupled pumps offer a simple and cost effective solution to sealing toxic, noxious, crystallizing or most other fluids that present problems for single seals and would therefore require use of a double mechanical seal. Magnetically-coupled pumps eliminate the need for cooling loops that are required by double mechanical seals. Two problems commonly associated with cooling loops are selecting a compatible barrier fluid and disposing of the barrier fluid in the event of an inboard seal failure.

Liquiflo has been producing magnetically coupled pumps for more than twenty years with ten's of thousands of successful applications. Magnetically-coupled versions are available for all of Liquiflo's product lines: 2, 3, 4, H-Series, Centry^® and Endura^®.
