Vertical valveless self-priming pump "SELFREE"


NSF/NSF-LR Self-priming centrifugal pump  YD-NSF、YD-NSF-LR series


There is no trouble caused by heat generation, abrasion or liquid leaks, becuase of Sealless pump without sliding parts.
Corrosion-resistant resin (CFRPP) is adopted on Wet Parts Kit, Pump base, Motor bracket, etc. It is possible to transfer strong acid, strong alkaline liquid, saline liquid, etc.
It is heat expansion absorption mechanism and possible to transfer high temperature liquid, because the resin is high corrosion-resistance.
It has self-priming and suction ability to be possible to transfer liquid smoothly, even if the liquid is at high temperature.
The shaft is no contact with any places. That is why there is no trouble caused by heat generation or abrasion for dry running.
NSF-LR (with linear seal)
It is sealless by magnet repulsion during operation. At the stop, the seals adhere by magnet force.
Self-priming/deadhead operation is available.
Examples of Use
For transferring/circulating liquid to heat exchanger/filter for plating solution
For pumping liquid up from drain pits or chemical liquid tanks
NSF-LR (with linear seal)
For glass abrasive/liquid with slurry
NEMA motor available
