FFC ESC Series End-suction Centrifugal Pumps
Summary of FFC ESC Series End-suction Centrifugal Pump Products

ESC type "three-section lifting-free pump", its unique design is the most advanced horizontal end-suction pump in the air-conditioning industry, with the characteristics of lifting-free, energy saving, space saving and maintenance saving. ESC pump is a single stage, single suction, horizontal centrifugal pump. Product structure is unique and novel, product performance is advanced and reliable, product quality is stable and durable, is the world's leading high-efficiency energy-saving products. Especially suitable for HVAC, air conditioning and other industrial circulating cooling water and other occasions.

FFC ESC pump is suitable for water supply, industrial pressurization, industrial liquid transportation, HVAC (heating, ventilation and air conditioning) and irrigation.

Applicable to the following environments:

District heating plant

Apartment heating system

Air conditioning system

Refrigeration system

Washing system

Other industrial systems

Product characteristics

The pump has the advantages of simple structure, compact structure and small floor area. It is a centrifugal pump that can be quickly disassembled and repaired.

The pump adopts the excellent hydraulic model of Iverson Group, UK. It has the characteristics of high efficiency, energy saving, stable quality and low noise. It is the world leader in pump performance. Pumps can not be loaded within the full range of performance, especially suitable for HVAC systems, industrial cooling systems and occasions with changeable working conditions.

The pump adopts the famous brand mechanical seal to ensure that the pump works without leakage for a long time, thus improving the working environment of the pump station.

The pump adopts the special structure of balance of axial force and radial force. The impeller is tested and balanced before assembling so as to minimize the force on the pump shaft. It not only ensures the smooth and reliable operation of the pump, but also prolongs the service life of the mechanical seal and motor bearing of the pump.

For small and medium-sized motors, maintenance-free imported bearings do not require lubricating oil. For medium and large motors, grease lubrication can be used to replace lubricating oil without shutdown. Therefore, the maintenance of this product is simple.

Working conditions

The standard design working pressure of the pump is 1.0 MPa (gray iron pump body). By changing the material of the pump body (ductile iron, cast steel, stainless steel, etc.), the working pressure of the pump can be increased (1.6 MPa or 2.4 MPa). The inlet and outlet flanges of pumps conform to PN-16 national standard flanges. If the work pressure is 1.6 MPa or higher, it must be noted when ordering, otherwise it will be supplied according to the work pressure of 1.0 MPa.

Applicable medium: Clean liquid (such as antifreeze) with clear water or similar physical and chemical properties to water.

The range of liquid transported by water pump is from - 25 ~140 ~C. The allowable temperature of liquid transported depends on the type of pump and seal.

Pump performance range

Flow range: 30-2100m_/h

Head range: 10-200 M

Outlet diameter: 50mm-350mm

Efficiency: up to 90%

Power: 4-200kw

High reliability:

The standard material of FFC ESC pump impeller is stainless steel 304, which can provide higher material. The impeller adopts closed structure. Its hydraulic model is excellent, its efficiency is high and its cavitation resistance is strong. Static and dynamic balancing calibration is carried out before each impeller is assembled. The calibration level is G6.3 or higher. FFC advanced design, strict quality system and high standard assembly technology provide strong guarantee for ESC pump quality reliability.

Design information

Pump body

Most pump body models adopt double volute shell design, which effectively reduces the radial force on the impeller of the pump. Especially in small flow operation.

The blocking vane is designed at the inlet of the pump body, which effectively reduces the pre-rotation at small flow rate and improves the performance at small flow rate.

High efficiency

The excellent hydraulic model of the company is selected, and the precision casting process is adopted to make the impeller flow channel smooth and smooth, thus ensuring the high efficiency and energy saving of the pump (the maximum efficiency can reach 90%).

The impeller is cut according to the performance required by customers, and the pump performance meets 100% of the customer requirements, thus ensuring the long-term, efficient and energy-saving operation of the pump.
