SK-M-PEN Series of Standard brands have different Models  SK-M-PEN150;  SK-M-PEN300; SK-M-PEN450; SK-M-PEN600; SK-M-PEN750;  SK-M-PEN1000; SK-M-PEN1500; SK-M-PEN3000; SK-M-PEN7000 Which can be applied to different usage, it can be integrated into the existing production line, also be used in desktop dispensing.All the SK series was produced under the principle of screw pump with self-sealing function. The spiral structure makes the material conveying very gentle.The material transported through SK series products will be almost without any shearing force.Even if the high viscosity material SK series products can also make the high viscosity material perfect back suction through the rotor rotation .Cleaning dispensing valve and mixing point rubber valve is very convenient, material replacement can also be completed quickly.

Function principle

SK-M-PEN adopts spiral structure design, pressure-resistant seal, rotor and stator are self-sealing design, easy to replace.The rotor is rotated in the stator cavity to realize the conveying function. The conveying process does not produce a shearing effect on the medium, so it does not affect the dielectric properties.At the same time can be reversed by the motor, easy to achieve the media back-suction function, to ensure that the media and material clean, completely solve the media dripping, drawing problems.

(1)  The maximum working pressure is proportional to the self sealing force and viscosity, which can be calculated by the data provided by the manufacturer. 

(2)  The transport rate is proportional to the speed of the micro pump.

(3) Volume flow depends on viscosity and primary pressure.

1) How does infinite loop piston work?

Standard dispensing screw valve belongs to rotary volume pump group. The operation is based on the infinite cyclic piston principle, which conveys the product from the suction end to the release end, thus establishing a pressure difference. The core of each application is a volumetric conveying metric screw valve. The rotor with eccentric motion and adapted to the characteristics in conveying and dosing, the interaction of the stator which corresponds to the condition of the application result of the unending motion piston, because of the geometrical measurement, the constant is always proportional to each turn,and by changing the direction of rotation can change the direction of transmission, so the volume is determined by the angle.

In addition, our technology provides a pressure-stabilized, linear-head pump capacity curve. This makes it clear that the operating rate, time and emission ratios are present. Thus this kind of pump is a revolution in both time and use, and is more widely used with constant dose transport applications. This metering pump has an accurate output measurement of 1% (different media), and the practical operation can be better controlled.

Another advantage is that the resulting conveying cavity, whose volume remainsunchanged throughout the movement. As a result, even solids and even bulk media can be transported. In addition, our pump technology provides additional benefits for other conveying mechanisms. For example, in more than 95% of all applications, no padding and dosing valves (metering valves) are required, and a short reverse motion at the end of the metering process can cause the line to disconnect or stop leaking.

2) What kind of medium can be dosed with the SK-M-PEN series?

1 Light cured epoxy resin, toluene, phenol, production agent, heat curing, gasoline, high filling liquid,

2 Shear sensitive adhesive, LED resin taste, hot conductive paste, solder paste, room temperature vulcanized rubber, silver paste, flux

3) Industrial oils, perfumes, cosmetics and pharmaceuticals, biological suspensions, silicone, lubricants, alcohol, MEK, thermal grease,

4 Polyurethane, solder paste, paint and ink, primer, acetone, epoxy, electrolyte solution, isopropyl alcohol and so on.

3) What can be the reason for too little or no flow of medium?

(1) Potential cause: Motor (dispenser cable) is not connected     

    Correction: Connect motor to eco-CONTROL unit Check all connections!

(2) Potential cause: Dosing needle is blocked, dosing needle is bent     

    Correction: Clean and replace the dosing needle 

(3) Potential cause: Medium has hardened / cured     

    Correction: Clean the dispenser     

(4) Potential cause: The dosing needle is too small or too long    

    Correction: Use a different dosing needle cross-section Reduce Dosing speed / flow rate 

(5) Potential cause: Insufficient supply of medium     

    Correction:Increase the supply pressure.Check for air-bubbles.Check the hose line.

(6) Potential cause: Stator is swollen     

    Correction: Check material resistance, contact manufacturer 

4) Why is it leaking or spilling after delivery ?

(1)Potential cause: Reverse flow not properly adjusted

   Correcting: Adjusting the reverse flow (instructions in the Operation manual)

(2)Potential cause: Bubbles in Media

   Correction: Ventilation medium

(3)Potential cause: Media is compressible

   Correction: Medium degassing.
