Split Mechanical seal for water treatment pumps
Split Master is a mechanical seal with an outside split structure, and by adopting our original special carbon, it can support non-flushing operation and full water level full speed operation (preceding standby operation).
Split Master is a mechanical seal with an outside split structure, and by adopting our original special carbon, it can support non-flushing operation and full water level full speed operation (preceding standby operation).
Applicable equipment
It can be used as a non-flushing shaft sealing device for various water treatment pumps such as vertical mixed flow pump, vertical volute type mixed flow pump, and horizontal between bearing (over-hung) type pump.
Merit
Improved embedding
Incorporation was the weak point of the conventional outside split seal. Split Master has greatly improved the ease of incorporation and exchangeability of the seal by our original Split technology.
No need to disassemble the pump when replacing the seal
Consumables such as Sliding material and "O" rings have been cut. It is a mechanical seal with a split structure, which is indispensable as a shaft seal device for vertical pumps and large diameter pumps.The bearing mount and large motor above the seal can be replaced as they are.
Can be driven in the air
We have adopted special carbon made by our original technology, which is a carbon manufacturer. Since there is little friction and heat generation is small, it corresponds to all water level full speed operation (preceding standby operation).
Non-flushing operation possible
Non-flushing operation is possible by adopting special carbon slurry resistance, low heat generation and static structure.Flushing piping and associated electrical and wiring equipment can be omitted, contributing to simplification of the airport.The cost of water injection and the management burden associated with maintaining water injection are reduced.The pump can be operated even in the event of an unforeseen situation such as a water outage.

Split Master usage example
Pump type | Shaft diameter （Mm） | Fluid | pressure (MPaG) | Number of rotations (Min-1） | Effect |
Wait ahead | φ180.5 | rainwater | 0.16 to 0.3 | 328 | Applicable to leading standby pumps.Supports pre-standby operation and non-flushing operation.Contributes to simplification of the airport, improvement of reliability, and reduction of maintenance costs. |
Vertical spiral mixed flow | φ150 | sewage | 0.135 | 590 | Applies to Sewage pump. Supports non-flushing operation.Contributes to simplification of the airport, improvement of reliability, and reduction of maintenance costs. |
Vertical diagonal flow | φ160 | rainwater | -0.03 ~ 0.05 | 260 | Applies to Storm sewage pump. Supports non-flushing operation.Contributes to simplification of the airport, improvement of reliability, and reduction of maintenance costs. Applies to Storm sewage pump. Supports non-flushing operation.Contributes to simplification of the airport, improvement of reliability, and reduction of maintenance costs. |
Horizontal axis swirl | φ100 | sewage | Negative pressure ~ 0.4 | 1750 | Applicable to sewage relay pumps. Supports non-flushing operation.Since the external water injection source was clean water, the annual water injection cost was reduced by about 60 yen. |
- There is no need to disassemble large equipment when replacing the seal, which contributes to cost reduction by shortening the work time.
- With the conventional Split Seal, the difference in sealing performance due to the built-in accuracy was remarkable. Split-Master is popular because it can reliably incorporate Split Seal by adopting its own processing technology and built-in jig.
