A leading open corrugated cardboard manufacturer relied on SAMOA diaphragm pumps for glue transfer applications during its manufacturing process. This renowned company, boasting over 30 plants and 4000 employees, produces all kinds of open corrugated cardboards, including grease-resistant, waterproof, or self-adhesive.
After testing pumps from two competing brands for pumping glue known as corrugating adhesive with low viscosity, they were not satisfied. They experienced serious issues with ice formation and pulsations, which could imply slow air motor operation, pressure loss, and therefore costly inefficiencies for the company. Additionally, the problem of pulsations increases vibrations in the system’s pipes and could even damage the pumped fluid. Moreover, the competition did not provide readily available spare parts.

Así afrontamos el proyecto
To address the challenges of pumping glue, a 2" pneumatic double diaphragm pump from the SAMOA PIVOT series with part number UP20A-BFC-NNN has been installed. The central body and air chambers are constructed from aluminum, while the fluid chambers and manifolds are made of ductile iron. All wetted parts are composed of Nitrile (Buna-N), offering excellent resistance to oils and greases. Additionally, the pump's material resistance can be configured to suit specific application requirements. With a flow rate of 650 l/min, the pump's bolted construction ensures optimum sealing to prevent leakage.
The PIVOT Series Air Distribution System has shorter and oversized evacuation air passages that effectively evacuate air from the chambers to the atmosphere, preventing freezing. Its operation is reliable and prevents the pump from stalling. Maintenance is straightforward due to the low number of parts, and the cartridge design of the air valve simplifies the installation process.
La solución
After two months of continuous operation without incidents, it can be assured that the switch from the competition to our pump has been a success, as the customer is highly satisfied for the following reasons:
- SAMOA´s UP20 requires less air supply and consumes less air than the competitor´s pump they had before to provide the same flow rate. This results in less wear, an increased service life of the pump’s moving parts, and lower energy consumption for SAMOA’s pumps compared to the competitor´s model.
