Model Description
IRG100-65J-200A
IRG-Single Stage Single Suction Hot Water Centrifugal Pump
100-suction port diameter (mm)
65-outlet diameter (mm)
J- indicates that the motor speed changes
200-impeller nominal diameter (mm)
A- indicates that the impeller diameter is changed (B and C respectively indicate the second, secondary cutting impeller)
IRG type hot water pump structure type
The pump is horizontally mounted, horizontally axially inhaled and spouted upwards. The pump body is a rear-opening type that can be repaired without disassembling the pump body, suction and discharge pipes. The shaft seal of the pump is sealed with a packing or mechanical seal. The bearings are rolling bearings and are lubricated with thin oil. There are two kinds of pump cover, one is the internal water sealing hole, and the other is the external water sealing. It must be specified when ordering.
The direction of rotation of the IRG type hot water pump is seen from the motor end, and the pump rotates counterclockwise.
IRG type hot water pump main parts material pump over-current parts material, generally gray cast iron.
IRG type hot water pump complete range
Complete supply pump, motor, common base, coupling, and provide check valve, gate valve, low valve, spout cone, whether it is equipped with spout pipe, the user must indicate according to the pipeline device.
Working conditions
1. Suction pressure ≤1.0MPa, or pump system high working pressure ≤1.6MPa, i.e. suction pressure + pump head ≤1.6MPa, pump static pressure test pressure ≤2.5MPa, please indicate the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6MPa, it should be separately proposed at the time of ordering, so that the over-flow part and the connecting part of the pump are made of cast steel material during manufacture.
2. Ambient temperature <40°C, relative humidity <40%.
3. The volume of solid particles in the medium to be transported does not exceed 0.1 per unit volume, and the particle size is <0.2 mm.
Note: If the medium is made of fine particles, please specify when ordering, so that the factory adopts wear-resistant mechanical seal.
