3 DF 5z DF 6z IG PERFORMANCE STAINLESS STEEL PUMP DF SERIES orizontal multistage pump PUMP DF Pumps are non-self priming, horizontal, multistage, end-suction centrifugal pumps. The pumps are of the close-coupled type and pump impellers are installed on motor shaft. The impeller, chamber and filling plugs are made of stainless steel. The DF pumps are available in various sizes and numbers of stages to provide the flow and pressure required. The DF pump are designed for the needs of commercial and industrial applications. MOTOR TEFC motor 2-pole Protection class : IP55 Insulation class : F Standard voltage, 5z : V V/38-415V Standard voltage, 6z : V V/38-415V Operating conditions - Pumped liquid Thin and clean non-flammable and non-explosive liquid without solid granules and fibers. - Liquid temperature : Normal temperature type : ~+7 ot water Temperature type : +7 ~+11 - Ambient temperature : up to +5 - Max.operation pressure : 1bar Application - Pressure boosting system - Domestic water supply systems - Cooling systems - Air-conditioning systems - orticultural irrigation systems - Small industrial water supply systems Definition of model DF 4 3 M DFNQ 4 3 M Single phase, 22V (Without M, 3 phase) Stage 1 Rated flow (m 3 /h) orizontal type Built-in variable frequency drive: SQ : SQ Drive NQ : NQ Drive Section drawing Construction No. Parts Material AISI/ASTM Inlet part Cast iron AISI34 2 Plug AISI34 3 Impeller AISI34 4 Shaft AISI34 5 Outlet part Cast iron AISI34 6 Mechanical seal 7 Motor flange Aluminum alloy Connection DF 2 DF 4 DF 1 Inlet part G1 G1 1/4 G1 1/2 Outlet part G1 G1 G1 1/ Base plate Stay bolt Diffuser Support diffuser Sleeve Steel AISI115 AISI34 AISI34 AISI34 AISI34 * Option : No.1,5 available DOOC PUMP 2

4 DFNQ DFSQ DFNQ DF 5z DF 6z IG PERFORMANCE STAINLESS STEEL PUMP DFSQ DF-NQ, DF-SQ Pump The DFNQ, DFSQ pumps are built on the basis of DF pumps. The main difference between the DF and DFN(S)Q pump is the variable frequency drive(nq, SQ-Drive). Enhanced with NQ-Drive/SQ-Drive, DFNQ/DFSQ pump together with the appropriate sensor is turned into an intelligent, variable speed pumping system. The NQ(SQ)-Drives are frequency converter integrated into the pump which adjusts motor speed so as to constantly provide users with the constant pressure or differential pressure to the flow rate. Versatile application DFNQ, DFSQ pumps are ideal anywhere you need an integrated pump solution, in variable-load operations, and in applications where a high degree of process control is of the essence. They are typically used in the following industrial and commercial building applications : eating and air-conditioning systems Pressure boosting systems Industrial recirculation systems Process systems with fluctuating load Benefits The DFNQ(SQ) pumps offer these obvious benefits. Energy consumption curve at varying pump speed Maintains constant pressure - Regardless of fluctuating demand. Energy saving up to 5% - Variable speed based on water demand. Extends life of pump and motor - Soft start functionality to minimize mechanical stress on pumping system. Simplicity - Eliminate the need for separate control panel, bypass-lines and control valves. energy consumption energy reduction energy reduction pump speed pump speed Pump operation speed % 3 DOOC PUMP
