Spirax Sarco Series V Pumps

The Sarco Series V Condensate pumps are used in low pressure heating systems to collect and quickly return condensate to the boiler feed unit. Their pumping 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 condensate 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 centrifugal 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 available 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 and VA.

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 250F, 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). 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 serviced 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.
