TPRNPump TPR_N is a kind of vertical non-self priming multistage centrifugal pump, which is driven by a stan-dard electric motor. The motor output shaft directly con-nects with the pump shaft through a coupling. The pres-sure-resistant cylinder and flow passage components are fixed between pump head and inlet & outlet section with stay bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equ-ipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload.

Motor• Full-enclosed air-blast two-pole standard motor • Protection class: IP55 • Insulation class: F • Standard voltage:50Hz: 1 x 220-230 / 240V 3 x 200-220 / 346-380V 3 x 220-240 / 380-415V 3 x 380-415V

Operation conditions• Thin, clean, non-flammable and non-explosive liquid containing no solid granules and fibers. • Liquid temperature: Normal temperature type: -15°C~+70 °C, Hot water type: -15°C~+120°C • Ambient temperature: up to +40°C • Altitude:up to 1000m

Application TPR_N is a kind of multifunctional products. It can be used to convey various medium from tap water to industrial liquid at different temperature and with different flow rate and pressure. TPR_N is suitable for slightly corro-sive liquid. • Water supply: Water filter and transport in Water-works, boosting of main pipeline, boosting in high-rise buildings. • Industrial boosting: Process flow water system, clean-ing system, high-pressure washing system, fire fighting system. • Industrial liquid conveying: Cooling and air-condition-ing system, boiler water supply and condensing system, machine-associated purpose, acids and alkali.• Water treatment: Ultrafiltration system, reverse osmo-sis system, distillation system, separator, swimming pool. • Irrigation: Farmland irrigation, spray irrigation, dripping irrigation.

TPRNMax. Ambient temperature When the pump operates under ambient temperatu-re higher than 40°C or under altitude higher than 1000m, because of low air density and poor cooling effects, the motor output power P2 will be decreased to certain ext-ent. If the pump is operated under the above-said condi-tions, it should bc cquipped with motor of higher power.

TPRNMinimum inlet pressure NPSH In case that the pressure in pump is lower than the steam pressure used to convey liquid, the cavitations will occur. To avoid cavitations, a minimum pressure at the inlet side of the pump shall be guaranteed. The maximum suction stroke can be calculated with following formula: H=Pb X 10.2-NPSH-Hf-Hv-Hs Pb=atmosphere pressure [bar] (can be set as 1 bar) In a closed system, Pb means system pressure [bar] NPSH=Net positive suction head [m] (It can be read out from the point of possible max. flow rate shown on NPSH curve) Hf=Pipeline loss at the inlet [m] Hv=Steam pressure [m] Hs=Safety margin=Minimum 0.5m delivery head If the calculated result H is positive, the pump may run under the max. Suction stroke H. In case the calculated result H is negative, a delivery head of min. Inlet pressure is necessary.

Operation in parallel Connecting several pumps in parallel running will benefit much more than running a single large pump.• Applicable to different working states necessary in a variable flow system. • Increasing the possibility of water supply when the pump is in failure. Because in case of pump failure, only part of the system flow is cffected.

Two pumps or more can be connected in parallel runni-ng if necessary.

Pump materialSelect the material variant on the basis of the liquid to be pumped.TPR series divide into three types: TPR, TPR(S), TPR(N):‧TPR is suitable for clean non-aggressive liquid. For example water and light oil.‧TPR(S) is suitable for light aggressive liquid; all of wetted parts are stainless steel.‧TPR(N) pumps are suitable for industrial liquids.

Pump connections Selection of pump connection depends on the rated pressure and pipework.To meet any requirement, the TPR,TPR(S) and TPR(N) pumps offer a wide range of flexible connections.‧DIN flange‧PJE Coupling ( Victarlic )

Shaft sealHow to chose the right Mechanical Seal‧Liquid Type‧Liquid Temperature‧Max Pressure

Operating pressure and inlet pressureDo not exceed the limit values for these pressures:‧maximum operating pressure‧maximum inlet pressures

Minimum inlet pressure, NPSHCalculatio of the inlet pressure "H" is recommended in these situations:‧The liquid temperature is high.‧The flow is significantly higher than the rated flow.‧Water is drawn from depths.‧Water is drawn through long pipes.‧Inlet conditions are poor.To avoid catitation, make sure that there is a minimum pressure on the suction side of the pump.H = Pb x 10.2 - NPSH - Hf - Hv – Hs

If the calculated "H" is positive, the pump can operate at a suction lift of maximum "H" metres head.If the calculated "H" is negative, an inlet pressure of minimum "H" metres head is required.

Note :To avoid cavitation, do not select a pump with a duty point too far to the right on the NPSH curve.Always check the NPSH value of the pump at the highest possible folw.

Guidelines to performance curvesThe guidelines below apply to the curves shown on the following pages:

Tolerances to ISO 9906:1999, Annex A, if indicated. The motors used for the measurements are standard industrial motors.Measurement s have been made with airless water at a temperature of 20 °C.The curves apply to the following kinematic viscosity: = 1 mm2/s (1 cSt).Due to the risk of overheating, the pump s should not be used at a flow below the minimum flow rate.The QH curves apply to a rated motor speed of a three-phase mains-operated motor.

The curve below shows the minimum flow rate as a percentage of the rated flow rate in relation to the liquid temperature. The dotted line shows a TPR pump fitted with an air-cooled top assembly.
