Multistage Pump is Bangladesh wilo is number 1 brand. Wilo Multistage, non-self-priming, horizontal high-pressure centrifugal pump in block design with horizontal suction- and vertical pressure port. The pump has a compact design with a continuous motor pump shaft and a bidirectional mechanical seal. The pump is suitable for water supply and pressure boosting, industrial recirculation systems, process water and cooling water circuits. It can also be used in washing systems as well as for irrigation.
- Mains connection 1~230 V (±10 %), 50 Hz or optionally 220 V (±10 %), 60 Hz
- Mains connection: 3~230 V (±10 %), 50 Hz (Δ) or optionally 265 V (±10 %), 60 Hz (Δ), 400 V (±10 %), 50 Hz (Y) or optionally 460 V (±10 %), 60 Hz (Y); efficiency class: IE2 same motor also: 3~220 V (±10 %), 60 Hz (Δ), 380 V (±10 %), 60 Hz (Y); efficiency class: IE1
- Fluid temperature of -15 to +110 °C
- Max. operating pressure 10 bar
- Max. inlet pressure of 6 bar
- Protection class 1~: IP X4; 3~: IP 54
- Nominal diameters of pipe connections: Rp 1, Rp 1 ¼ or Rp 1 ½, depending on type
Note on inlet pressure
The maximum inlet pressure is calculated by subtracting the maximum delivery head of the pump at Q= 0 from the maximum operating pressure of the system.
Note on materials
1.4301 corresponds to AISI 304, 1.4404 corresponds to AISI 316L.
