pump operation completely unaffected by water temperature or density. Some pump curves show PSI vs GPM or PSI vs lbs./hr. These curves are not general, but specific, and require definition in terms of water temperature and density. PSI curves are sometimes used for boiler feed pump description but sho uld not be used in selecting pumps for Heating-
Jan 01, 2016 · SVMIT, BHARUCH-392001, India Abstract The present works discuss the comparison between the analytical and experimental performance curve of the high pressure boiler feed pump - a multistage centrifugal pump. The hydraulic loss model stated by J.F. Gulich is widely used for the analytical performance prediction of the single stage centrifugal pumps.

Engineering Design Guide: GBHE-MAC-1504 Boiler Feedwater Pumps Information contained in this publication or as otherwise supplied to Users is believed to be accurate and correct at time of going to press, and is given in good faith, but it is for the User to satisfy itself of the suitability of the information for its own particular purpose.
PEC Pumps specialized in manufacturing Boiler Pump, which ensure maximum suction with a capacity of 8 Wmc. Offered at industry leading price, these pumps come with bush bearing at rear end and ball bearing at end. Use of quality cast iron and bronze have made Boiler Feed Pumps robust, durable and in line with prevailing quality standards.
Proposed in this paper is a prediction model to estimate the suction flowrate of a boiler feed pump. The prediction model is developed by using the multiple regression technique, and consists of a response variable (Suction flowrate) and eight candidates of predictor variables (Discharge pressure,
Boiler feed pumps discharge water into a boiler drum. In turn, the boiler heats up the water and turns it into steam. In functions like these, boiler feed pumps must be strong enough to handle varying temperatures to function well. Aside from temperature, boiler feed pumps need to handle different feedwater flows and intense water pressure.
DG boiler feed water pump is widely applied to supply water of low or high pressure boiler. It is also used for high pressure water supply and drainage of industrial and urban. The temperature of medium delivered should be in the range of -20°C to 150°C and the water pump inlet pressure should be less than 0.6M Pa. Flow: 6.3-450m3/h.
The centrifugal-pump is designed with single stage and double suction impeller. The requirements for the centrifugal pump are it should develop the 475 m of head with 2135 m3/h flow rate while running at 4200 rpm. The schematic view of the centrifugal pump casing with impeller is shown in Fig.1. The casing has trapezoidal section for volute shaped
May 25, 2012 · A centrifugal boiler feedpump with a double-suction was tested and the cavitation characteristics were visualized and compared with the calculated results at three pump operating points of 0.63Q opt, Q opt and 1.50Q opt, respectively. As a result, the calculated pump performance drop and cavitation behavior agree well qualitatively with the

The hydraulic loss model stated by J.F. Gulich is widely used for the analytical performance prediction of the single stage centrifugal pumps.
BOILER FEED PUMP BFP is the most power consuming auxilliary of the power plant placed at the ground floor. BFP is located in the feed water cycle and pumps the demineralised feed water from deaerator to economiser inlet header. This system also supplies desuperheating water to boiler …
multistage pump in the world, is ideally suited for boiler feed service. Vertical turbine and double suction pumps can handle the most demanding condensate or circulating water needs. Sumps can be cleared with Goulds Pumps' line of vertical or submersible sump pumps. Heavy duty slurry pumps like the XHD, SRL and 5500 are
Jul 18, 2018 · Conditions required to start up the boiler feed pump unit: (1) Feed water tank filled (to above minimum water level) (2) The pump and pipings are fully primed and vented. (3) Suction valve fully open. (4) Discharge valve closed. (5) Minimum flow shut-off valve open. (6) Cooling water system running. (7) Oil pump in operation.
Jul 25, 2017 · 25 Below criteria can be used for pump selection also: Centrifugal Pumps (Process Pumps) Medium to high capacity for low to medium head requirements Higher head requirements can be met by using multistage impellers. General Service for all liquids, hydrocarbons, products, water, and boiler feed. Simple, low cost, even flow, small floor space
BOILER FEED SYSTEM OPERATION AND 4. Wrong direction of rotation – compare pump rotation with arrow on pump. 5. Clogged suction line or inlet strainer – Inspect, clean if necessary. B. INADEQUATE CAPACITY OR PRESSURE 1. Mechanical wear or damage – rotate the pump by hand to check for tight Verify that water flow rate is not too
