TYPE .005 DA-IST ATMOSPHERIC DEAERATING BOILER FEED UNITS WITH
STAINLESS STEEL Spray Box AWF PUMPS, And DIRECT INJECTION STEAM HEATING ASSEMBLy, AND A SHELL & TUBE VENT CONDENSER
CAPACITY SCHEDULE MUST BE COMPLETED.
Furnish and install according to drawings and manufacturer’s instructions the quantity of .005 DA-IST deaerating boiler feed units as shown on the drawings. Unit shall have a capacity of ____ pounds of steam per hour. The system shall be of the single tank design and guarantee oxygen removal to not more than .005 ccs/liter in the effluent throughout all load conditions between 5 and 100%. The deaerator shall be designed for atmospheric operation suitable for use with pumped and gravity returns. Pressurized designs are not acceptable. Each unit shall consist of (1) steel receiver with a quantity of _____ boiler feed pumps, (1) direct injection steam heating assembly, (1) spray manifold in a 300 Series stainless steel spray box, (1) modulating make-up assembly, electrical controls and accessories.
The boiler feed receiver shall be of welded steel minimum ^3/_16" thick construction, elevated to meet the NPSH requirements of the boiler feed pumps (with 2 ft of safety factor), horizontal with convex flanged and dished heads. The receiver shall be supported by steel tubing and have a capacity as shown on the drawings. The boiler feed receiver shall be equipped with the following: (1) top and bottom shut-off water level gauge with automatic shut-off if glass is broken, (1) dial thermometer with separable well, (1) isolation valve between receiver and pump plus a valve  in each bleed line installed for maintenance, (1) manhole for tank inspection, (1) stainless steel chemical feed quill, (1) sampling valve, (1) externally mounted high and low level alarm switches and low water cut-off switch and (1) magnesium anode. A suction isolation valve and an expansion coupling shall be installed in the suction piping between the receiver and the pump(s) to permit servicing the pump(s) without draining the receiver. The individual pump suction piping (manifolded suction lines not acceptable) must be sized for a velocity of 2.9 ft./sec. or less and contain no suction strainers. A liquid filled discharge pressure gauge with snubbers shall be provided for each pump.
All controls switches and valves to have a NEMA _____ rating.
A 300 Series stainless steel deaeration spray box with integral cascade trays containing a spray manifold with stainless steel spray manifold and nozzles shall be flange mounted to the boiler feed receiver. A dial thermometer and a pressure gauge shall be an integral part of the manifold assembly.
A shell and tube vent condenser shall be installed on the deaeration to reduce the steam vent loss to trace amounts. The vent condenser shall preheat the incoming effluent to reduce the steam consumption of the main heating assembly.
A modulating water make-up assembly shall be installed on the receiver. The assembly shall consist of a controller, transmitter and valve with a three-valve manual bypass and wye strainer.The capacity of the transfer valve shall be equal to 100% of the load in case of emergency where no returns are present, at a 50 PSIG supply pressure  with a 30 PSIG drop across the valve. Make-up assembly will also send 4-20mAmp signals remotely as needed as well as alarms.
A magnesium anode shall be mounted on the receiver to inhibit electrolytic corrosion and shall be mounted in a 1^1/_4" removable plug. The anode shall be at least 1^5/_16" diameter by 18” long.
A direct injection steam heating assembly shall be installed in the receiver. The deaeration assembly and the sustaining assembly shall consist of a double flanged mounted stainless steel injection pipe, steam control valve, temperature regulator, wye strainer and (1) compound gauge for measuring vacuum or pressure gauge on unit. The heating assembly shall be sized for the capacities and locations as shown on the drawings.
The centrifugal boiler feed pumps shall be mounted on the receiver suction piping. The pump shall be (Horizontal or Vertical) a multi-stage cast iron construction with bronze wearing rings. The impeller(s) shall be Bronze for long life and durability. The pump shall be flexible coupled permanently aligned with a C-face motor connected to the bearing housing which is C-face connected to the pump. The bearing frame shall be designed with grease fittings for bearing lubrication. Bearings shall be extra heavy ball type with high temperature grease. The pump shall be fitted with a seal flush line designed to keep the seal cavity pressure at or below 50 psig. The pump suction flange shall be an ASA design. The pump discharge shall be also be an ASA flange design. The Silicon Carbide/ Viton seal shall be rated for 300°F service. The entire pump shall be dynamically balanced to deliver its full rated capacity with _____ feet of NPSH. The pump shall have a NEMA standard shaft. The horsepower and electrical characteristics shall be as shown on the drawings.
Each boiler feed pump will have a factory installed automatic flow control valve in the discharge of each pump.
Each continuously running boiler feed pump 7^1/_2 HP and larger will have a factory installed bypass line with a stainless steel orifice.
The manufacturer shall furnish a certified pump performance and NPSH test. The pump manufacturer shall furnish complete elementary and connection wiring diagrams and installation and operation instructions.
The entire pump package will be U.L. labeled when a control panel is furnished.
Electrical control specifications must be added. See electrical specifications for boiler feed pumps.
Manufacturer shall be Shipco® PUMPS, P.O. Box 279, Shippensburg, PA 17257.
