Mepco (Formerly Dunham Bush) Centrifugal Pumps

MEPCO offers a complete line of Close Coupled, Base Mounted, and Inline Centrifugal Pumps that meet the latest standards for hydraulic performance and dimensional characteristics.  MEPCO pumps are ideally suited for a variety of applications, including heating, air conditioning, and pressure boosting.  An advanced impeller design maximizes hydraulic efficiency.  Each impeller is dynamically balanced for vibration free operation.  Pumps provide heads to 150 ft. and flows to 2000 GPM.  Custom designs are available for OEM applications.

Mepco (Formerly Dunham Bush) / Westco Turbine Pumps

The WESTCO regenerative turbine can be used for a wide range of services and applications due to its excellent suction characteristics, ability to handle entrained vapors/gases, high temperature capability without internal binding, high-pressure reserve and slower rotation assuring long life. Typical applications found in boiler houses, chemical plants, canneries, dairies, greenhouses, and cement plants, distilleries, breweries, boats/ships and factories. Bronze fitted construction comes as standard, but all bronze as well as all iron construction is available.

Mepco (Formerly Dunham Bush) Condensate Pumps

Vent-Rite Condensate Pumps are complete, compact assemblies which return water from atmospheric heating systems, boiler feed systems, low pressure steam process equipment or from any combination.  These pumps lift condensate from extremely low to high return lines and can generate impressive fuel savings by returning hot condensate to the boiler or boiler feed pump instead of wasting it to the sewer.  Further, by drastically reducing the amount of make-up water required, they conserve boiler chemicals and minimize difficulties from boiler encrustation.

The Vent-Rite Model CRV Condensate Pump is offered in simplex and duplex configurations in capacities ranging from 1000 to 100,000 EDR (2-150 GPM) in pressures from 10 through 50 PSI at 1750 RPM and 10 through 70 PSI at 3450 RPM.  Standard steel tanks are available in 10, 16, 24, 33 and 44 gallon sizes, with 70 and 100 gallon optional sizes available.  Cast iron tanks are available in 15, 21, 35, 50, 75 and 110 gallon sizes. A wide variety of accessories from customized control panels to isolation valves are factory available with this model.

Mepco (Formerly Dunham Bush) Vacuum Pumps

The vacuum pump is the heart of a steam heating system.  For either new construction or retrofitting of older systems, the rapid removal of air from the system speeds warm up while reducing fuel consumption.  The Vent-Rite E2 and C5 Units feature Vent-Rite designed 3450 RPM centrifugal pumps, jet-type exhausters, heavy gauge copper bearing steel receivers, and come complete with electrical controls and essential accessories.  The E2 and C5 units are manufactured in simplex or duplex configurations in capacities ranging from 5000 EDR (7.5 GPM) through 65,000 EDR (97.5 GPM).

Mepco (Formerly Dunham Bush) Boiler Feed Pumps

Controlled by the demands of the Boiler Water Level Controller, the Vent-Rite complete line of Boiler Feed Pumps are fully equipped units designed to efficiently return hot condensate and make-up water.  They may be used on low and medium pressure atmospheric heating systems, steam process equipment, or combinations of both.  Their use often permits increasing the usable heated space in a building by allowing the installation of radiation below the boiler water level.  Performing many of the same functions as a condensate pump, these pumps additionally provide increased storage capacity and automatic make-up response to meet boiler water demands.  Vent-Rite Boiler Feed Pumps are offered in an economy model and a complete premium line. 

The Vent-Rite Model AWL(CH) or AWL(TB) is the most popular of the boiler feed line.  An elevated tank in an "L" configuration gives unconfined discharge piping opportunities.  This pump is especially applicable where temperature of the condensate rather than space limitation is of concern.  This unit is available with centrifugal pumps as well as turbine pumps to match the exact GPM and PSI requirements.
