Water pump stations - Import export

Body and Cover : GG-25 Cast Iron / Handwheel: GG-25 Cast Iron / Gasket: EPDM / O-ring: EPDM / Spindle: Stainless steel / Segment Gear : GG-25 Cast Iron . ** Connection Type: Flanged / Working Pressure :175-300 PSI / Working Temp.:-10ºC , + 120ºC / Working Test Pressure : 600 PSI *** NRS gate valve is developed to be used as the cut off and zone control valves in order to substitute supervisory switched butterfly valves and OSY rising stem valves in the fire security systems. These valves are usually burried underground to prevent the risk of freeze. Just to make them visible and traceable inside the systems, they are preferred to be used with post indicators instead of wheels. **** Application Areas: In fire fighting systems, which is non-affected by freeze, than they are using under the soil.

We produce high quality water pumps. For further information please contact with us. We have wide variety of pump kinds.

Our Civil Engineering division has all the necessary know-how to build the most complex reinforced concrete structures. We use this know-how in the construction of bridges, pumping stations, water treatment plants, culverts, building foundations, storm water basins and overflows, or in the construction of special structures such as skate parks.

A pump is a mechanical device for moving a fluid from a lower to a higher location, or from a lower to a higher pressure area. The fluid can be any type of liquid or gas, and pumps may be classified in many ways according to their purpose, specifications, environment, design, etc. Pumps are used in a wide range of industrial and residential applications. Pumping equipment is extremely diverse, varying in type, size, and materials of construction. Classifications and Types: Pumps may be classified on the basis of the applications they serve, the materials from which they are constructed, the liquids they handle, and even their orientation in space. All such classifications, however, are limited in scope and tend to substantially overlap each other. A more basic system of classification first defines the principle by which energy is added to the fluid, goes on to identify the means by which this principle is implemented, and finally delineates specific geometries.

Refra manufactures pump stations for waterloop systems with the cooling capacity from 30 kw to 250 kW. These systems produce distributed cooling at different temperatures with a single condensing water loop. Together with Refra pump stations, the system creates a fully integrated refrigeration technology that eliminates the need for complex refrigeration systems and greatly simplifies installation work. Built on a super slim assembled galvanized steel frame with powder coating. Standard selection includes single or dual pump with inverter, glycol tank with filling pump, shut-off valves, control board with controller and necessary control sensors as well as a three-way valve, manometers and a coarse cleaning filter. Extra features, such as emergency heat exchanger with full controls or bubble filter separator can be combined. An additional heat recovery pump can also be added to extract maximum efficiency from the system.
