TI-5-304-US 4.15

Description Condensate pumps are used in low pressure heating systems to col-lect and quickly return condensate to the boiler feed unit. Their pump-ing action is controlled by the water level in the receiver. Simplex units consist of an electric motor close-coupled to a centrifugal pump mounted on a cast iron or welded steel storage receiver with a float operated pump control. Multiple pump units are used when greater pumping capacity or back-up pump protection is required.

Boiler feed pumps are used to pump and precisely control the con-densate and makeup water required by the boiler(s) in low pressure steam applications. Pumping action is controlled by the fluid level in the boiler. They consist of a cast iron or welded steel storage receiver equipped with a makeup valve and one or more close-coupled cen-trifugal pumps.

Spirax Sarco V series pumping systems are available in simplex, duplex, triplex or quadruplex configurations from 1,000 to 100,000

sq. ft. EDR capacities. Discharge pressures from 10-40 psi are avail-able on units equipped with 1750 rpm motors; 20-75 psi on 3500 rpm units. True 2 ft. net positive suction head pumps are available.

Receivers Cast iron, rectangular receivers are available with 15 to 110 gallon capacities.

Heavy duty, welded, rust resistant, copper bearing steel receivers are available in rectangular or cylindrical configurations with capacities ranging from 21 to 1,000 gallons.

Spirax Sarco Centrifugal Pumps Four centrifugal models are available in a large selection of sizes to meet your specific application requirements: VC, VJ, VE, VA and VN.

The pumps are bolted directly to the receiver to provide a compact efficient design. Their close-coupled, centrifugal design with bronze enclosed type impeller assures smooth, efficient water passage. A mechanical seal, rated to a maximum temperature of 250˚F, is vented to the receiver to assure adequate lubrication at all times.

An advanced impeller and volute design make many of the pumps excellent for applications requiring a true 2 ft Net Positive Suction Head (NPSH). These units are identified with shaded areas in the selection tables on TIS 5.306 & 5.307. The simple, reliable single stage construction eliminates the need for additional impellers and parts used in other low NPSH pumps.

Designed for long-life, low maintenance and reliable service, the pumps are easily serviceable if necessary. Parts subject to normal wear are readily accessible. Impeller and mechanical seal can be ser-viced without disturbing piping or electrical connections.

All pumps are close-coupled to heavy duty, ball bearing open drip proof electric motors. Fractional horsepower single phase motors have built-in thermal overload protection.

To help you determine the appropriate pump type for your applica-tion, specifications for each of the four types are described in the next paragraphs. Refer to selection tables for additional pumping system performance data.

Control Panel can be remote.

NEMA ENCLOSURES

Enclosures For Inside Non-Hazardous Locations

Provides Protection Against Type of Enclosure

1 2* 4* 12*

Accidental contact with enclosed equipment yes yes yes yes Falling dirt yes yes yes yes Falling liquids and light splashing yes yes yes Dust lint fibers and flyings yes yes Hosedown and splashing water yes Oil and coolant seepage yes yes Oil and coolant spraying and splashing Corrosive agents Occasional submersion

*These enclosures may be ventilated. However Type 1 may not provide protection against small particles of falling dirt when ventilation is provided in the enclosure top;

and Type 12, if ventilated, will not be dust-tight

TYPE 1 - GENERAL PURPOSE INDOOR

Nonventilated Enclosures

Type 1 enclosures are intended for use indoors primarily to prevent accidental contact of personnel with the enclosed equipment in areas where unusual service conditions do not exist. In addition, they provide protection against falling dirt. Enclosures which are intended to be flush mounted in building walls shall have provision to align the device with the flush plate and to compensate for the thickness of the wall.

Type 2 enclosures are intended for use indoors to protect the enclosed equipment against falling non-corrosive liquids and falling dirt. They shall have provision for drainage. If provision is made for the entrance of conduit at the top, it shall consist of a conduit hub or the equivalent. When completely and properly installed, these enclosures shall prevent entrance of dripping liquid at a higher level than the lowest live part within the enclosure.

Type 12 enclosures are intended for use indoors to protect the enclosed equipment against fibers, flyings, lint, dust and dirt and light splashing, seepage, dripping and external condensation of non corrosive liquids. There shall be no holes through the enclosure and no conduit knockouts or conduit openings, except that oiltight and dust-tiqht mechanisms may be mounted through holes in the enclosure when provided with oil-resistant gaskets. Doors shall be provided with oil-resistant gaskets. In addition, enclosures for combination controllers shall have hinged doors which swing horizontally and require a tool to open.

TYPE 4X WATERTIGHT & DUSTTIGHT INDOOR & OUTDOOR

Type 4X corrosion resistant enclosures are intended for use indoors or outdoors to pro-tect the enclosed equipment against splashing water, seepage of water, falling or hose-directed water, and severe external condensation. They are sleet-resistant but not sleet- (ice) proof. They shall have conduit hubs or equivalent provision for watertight connec-tion at the condiut entrance and mounting means external to the equipment cavity.

ENCLOSURES FOR HAZARDOUS LOCATIONS- GENERAL

The term “explosion proof” has been so loosely applied that NEMA deprecates its use.

As defined by the “National Electrical Code,” the term “explosion proof”applies only to Type 7 and 10 enclosures which, when properly installed and maintained, are designed to contain an internal explosion without causing external hazard. The term should not be applied to Type 8 enclosures which are designed to prevent an explosion through the use of oil-immersed equipment or to Type 9 enclosures which are designed to prevent an explosion by excluding explosive amounts of hazardous dust.

EXPLOSION PROOF - NONVENTILATED ENCLOSURES

Type 7 enclosures are intended for use indoors in the atmosphere and locations defined as Class I and Group A, B, C or D in the “National Electrical Code." The letter or letters A, B, C or D which indicate the gas or vapor atmospheres in the hazardous location shall appear as a suffix to the designation "Type 7" to give the complete NEMA designa-tion and correspond to Class 1, Group A, B, C or D, respectively, as defined in the "National Electrical Code." These enclosures shall be designed in accordance with the requirements of Underwriters Laboratories, Inc, "Industrial Control Equipment for Use in Hazardous Locations," UL 698. and shall be marked to show the Class and Group let-ter designations.

Type 9 enclosures are intended for use indoors in the atmospheres defined as Class II and Group E, F or G in the "National Electrical Code." The letter or letters E, F or G which indicate the dust atmospheres in the hazardous location shall appear as a suffix to the designation "Type 9" to give the complete NEMA designation and correspond to Class II, Group E, F or G, respectively, as defined in the "National Electrical Code."

These enclosures shall prevent the ingress of explosive amounts of hazardous dust. If gaskets are used, they shall be mechanically attached and of a noncombustible, nondete-riorating, vermin-proof material.
