KZF-M Dry Mechanical Seal

There are various types of motors such as electric motors, air motors, explosion-proof motors, and oil-less motors can be installed. You can choose from three body sizes: large, medium, and small. And select the most suitable stirring blade according to the application and purpose of stirring. The motor housing can also be used with the KZF-O series.

The dry mechanical seal type significantly reduces the contamination of seal wear particles into the liquid.
Since the sliding surface does not contact the stirring shaft, the rotational power of the shaft is not impaired.
The stainless steel body is resistant to rust and can be used in clean environments such as the pharmaceutical and chemical industries.
The seal life is long, and maintenance by lapping polishing of the sliding surface is possible in the event of wear.
The shaft can be attached and detached with minimal disassembly, shortening the time of assembly work.
With its high-strength flange structure, the large size (KZF-ML) can be mounted on large tanks of 1000L or more.

We select the most suitable motor according to the nature of the liquid, the purpose of stirring, the specifications of the tank, and the usage environment.

(1) What kind of liquid is stirred?	➡ Acidity? Alkalinity? Dangerous goods? etc
(2) What is the viscosity of the liquid?	➡Low viscosity? High viscosity? What is the stickiness? etc
(3) What is the amount of liquid?	➡What is the tank capacity? What is the shape of the tank? etc
(4) What is the purpose of stirring?	➡ Mixing? Anti-sedimentation? Emulsification? Variance? etc
(5) In what kind of environment will it be used?	➡ Explosion-proof environment? Clean environment? etc

Motor installation example

The KZF-M series can be equipped with various electric motors and air motors, and can also be used for explosion-proof motors and oil-less motors.

It can be widely supported by “small ~ large”, “low torque ~ high torque”, and “low speed rotation ~ high speed rotation”.

*1. A sliding noise peculiar to dry mechanical seals may occur, but it is not abnormal.
*2. The reference weight does not include motors and blades. Since the shaft length differs depending on the tank to be mounted, the weight is a reference value.
