Product Description
Electric ink pump
Electric ink pump can speed up the ink circulation, make the print better and decrease noise. It has many characteristics, such as simple structure, easy operation, little easy wearing parts, stable performance, safety, non-pollution and overload self-protection.

1. It is made of copper, rust-proof aluminum and stainless steel, special film can prevent many kinds of organic corrosive.
2. Do not need to extract water, because the hydroscopic property is good. And it can be used to transfer the liquid with big viscidity or solid particle.
3. It has the function of feeding back, washing quickly and saving material.

The scope of application:
The pump has been applied to upgrade to ink circulation system of water-based ink printing machine, photogravure press, flexographic printing machine and gluing machine. It can also be used in conveyor system for other kinds of liquids with different viscidity, such as water, oil, latex, liquid with solid particle and other kinds of corrosive liquids.

It takes the compressed air as power without the interference of spark, static and electromagnetism. So it can be place at inflammable and explosive places.

Pneumatic Diaphragm Pump for Printing Machine (QDM-902)

Pmeumatic diaphragm pump
Single-phase pneumatic diaphragm pumps is professionally applied for printing machinery.

Technical parameters:
Type: QDM902
Working pressure: 0.25- 0.6Mpa
Maximum transmission viscosity: 1000 centipoise
Medium import and export connection thread: G1/ 2
The intake connecting thread: G1 1/2 "or G1 1/4"
Biggest suction: Six meters
Single-phase pneumatic diaphragm pumps is professionally applied for printing machinery.

Installation method and the matters needing attention:
1. The pump must be installed vertically, pay attention to the direction of arrow
2. The ink mouth should connection with hose.
3. After the completion of the work, it need water or other decompose media to wash pumps, cleaning should process in operating condition.

This pump has left and right two groups of diaphragms, aim to separate the left and right surgetank with the medium convey cavit

Double-phase Pneumatic Diaphragm Pump

Field of application:
Printing: Ink(water-based, gravure), solvent (toluene, acetone ethanol etc), coating, adhesive liquid etc.
Papermaking: Cooking liquid, bleach, coating, adhesive liquid etc.
Others: Ptroleum chemical materials, fuels, chemical raw materials, acid and alkali, etc.

Technical parameters:
Working pressure: 0.15-0.8 Mpa
Maximum transmission viscosity: 1000 centipoise
Biggest suction: 8 meters
Medium in and out connection threads: G3 / 8 inch
The intake connecting thread: G1/4 inch
Outline dimension: 180 * 150* 135mm
Fixed feet in diameter hole: 8 aperture: 135 *95mm

Operating principle:
This pump has left and right two groups of diaphragms, aim to separate the left and right surgetank with the medium convey cavity. When the valve core of the reversing valve in the right place, compressed air into the left surgetank, meanwhile, the compressen air of the right surgetank will be outlet. Along with the increasing of left surgetank pressure, left diaphragm will extrusion towards left, to make increasing the pressure of the transmission cavity, the medium of the inner cavity through the single valve and convey upwards, then outlet by the exit, right transmission cavity single valve turn off.
Then the back valve corn of the renersing valve move to left, start the next transmit process, move in circles, therefore reach the working purpose of transmitting medium.
