Vertical Linear seal pump SLURRY PUMP

seriesseriesFeatures of SLURRY PUMPPLC

The pump does not have a mechanical seal or a gland packing as a seal. (Not contact)
Our original structure seals by liquid balance during operation and at the time of shutdown, a linear
seal blocks inside of the pump.

Rotating disk

1. There is no sliding parts during operation, so it resists abrasion by slurry, deadhead operation and dry running.
2. No need cooling water, because of no seal/packing.
3. There is no consumable parts such as a mechanical seal or a gland packing.
4. Proximity sensor and PLC protects the linear seal as standard.

Moval seal

※ MSagnet valve is also available as the option.

Cut seal

Double safety structure
Even if the moval seal is damaged or slurry getsstuck on the seal parts, there is the double safetymeasure that the phragm outside of the seal
minimizes liquid leakage.

Principle
At the time of shutdown

During operation

Balanced liquid by a back blade is rised by the backﬂow fromthe discharge outlet and the suction pressure, but a cut seal
reduces the pressure. Moreover, magnets in a rotating disk
attracts magnets in a moval seal. The contact between therotation disk and the moval seal trap air at the surface of theliquid. That is why the liquid does not rise to the seal face.

Magnets in the rotating disk changes the pole at the sametime as the rotation. They repel magnets in the moval seal
and the seal part opens.
The back blade of the rotating impeller makes the liquidbalance seal and there is only air above the back blade.
It makes parts no contact and no sliding.

At the time of shutdown, magnets in the rotating
disk with the shaft attract the magnets in the moval
seal and make a sealing eﬀect . A cut seal under thelinear seal protects backﬂow. The sealing face does
not contack liuqid and stop air.
The magnets in the rotating disk and the moval seal
repel and separate at the same time as the pumpstart. It comes into no contact and no sliding.

Proximity sensor

The pumpʼs suction head is 2 m as standard. However,the higher head may be available depending on the condition.
Please ask us.
Suction head(2 m or less)

The linear seal opens at the time of startup and comes into no contact at
the normal operation. The proximity sensor is incorporated for the safetymeasure as standard and monitors the sealʼs open/close. Even if the moval
seal does not open (at the state of no contact), it sends out signals.
< It starts to detect 2 minutes after starting operation. If the moval seal does
not open at the time (at the state of no contact), it sends
out signals.>※1 Install the pump automatic stop device by using thesignals.
※2 The proximity sensor and PLC have already connected.
