Since 1991, Sajo Technologies Inc. has been manufacturing press auxiliary equipment for the printing industry including the sheetfed and web offset industries. Our printing ink equipment includes ink dispensing systems ( ink levelers ), ink agitators, web break detectors, ink filters, ink meters and ink pumps for both conventional inks and uv inks.

Sajo offers a wide range of ink levellers for both sheet-fed presses and web offset presses. The ink levelers include one, two and three piece models as well as two and three stage versions designed for printers who don’t have the budget or justification for the complete automated ink leveler. In addition Sajo’s newest ink dispensing system is the new UV ink leveller ideal for both the web press and sheet fed press.

Sajo manufactures ink agitators in one and two piece designs for both sheetfed presses and web offset presses. The pneumatic ink agitator requires no electricity and can be mounted either over or in front of the ink fountain and requires very little space. The ink mixer agitates the ink with the use of a double band rodless pneumatic cylinder and using two adjustable paddles which can easily be removed for cleaning.

Through the association with its U.S. counterpart, Sajo has obtained the rights to the Quadtech web break detectors. The Quadtech web break detector utilizes ultrasonic sensors and color touch screen controls. The web break detection system instantly detects web breaks, simultaneously stops press operation, and fires web severers before costly web wrap-up damage can occur. The WebStop system can store up to 36 user-created jobs, allowing the system to be instantly re-configured for different press runs.

Sajo ink meters combine accuracy with reliability. Sajo offers two different ink meter designs, one that is built on the nutating disc principle, the other using elliptical gears. The nutating disc or positive displacement disc flowmeters are precision constructed measuring instruments used for accurate measurement of offset ink at high pressures. The rugged construction of the elliptical gear positive displacement flow meter series features stainless steel bodies and gears and tungsten carbide bushings and shafts.

Sajo Technologies have become distributors for both the Yamada Ink Pumps and Lincoln Ink & UV Ink Pumps for the sheetfed and web offset industries. They include 5 gal., 55 gal., tote and UV ink pumps. Unlike the canister style Sentinel System® with the capacity of only 7.5 lbs. per canister, the 5 gallon pumps which are ideal for the sheetfed industry hold up to 60 lbs. of ink at a time and include a low level alarm as well as a digital ink scale that can be zeroed at any time with a ± 2% accuracy.

Ink Filters help reduce hickies caused by impurities in the ink or deterioration of pump components. Sajo provides high pressure inline filters or “Y” filters with various flow ranges and micron sizes. All filters include replaceable stainless steel elements that are both inexpensive and easy to change.
