Lakewood, Washington – Specialty Products has upgraded its LPG low pressure proportioner for polyurethane and polyurea systems. First launched in 2009, the LPG has been subject to various upgrades over the years, and the latest version has a higher output pump.
The new machine has a maximum output of 4.5 l/min, compared to 2.8 l/min with the older versions. The higher output pumps can be retrofitted onto existing machines.
Custom pump options are available for specific applications, including a very low output pump with a flow of 0.95 l/min for spraying slow set polyureas, overhead and on vertical surfaces. A 9 l/min option is also available for high-output pour foam or polyurea applications.
The LPG machine was originally developed for the US government, to give troops a lightweight, portable machine to armour buildings and vehicles in war zones. It weighs about 40kg, and applies products such as spray polyurethane foam insulation, pour foam for the decommissioning of tanks and pipelines, and hydrophobic foam to raise concrete slabs. Other applications include spraying polyurea coatings and pouring polyurea for concrete control joints.
‘The larger pumps for increased output result in labour savings when compared to the original pumps,’ said Chas Weatherford, vice president at Specialty Polymers. ‘Additionally, with the higher output capability, the SPI Lock and Load gun still allows the applicator to simply adjust the output from zero to where ever they’d like, depending on their application, with the adjustable flow control dial.’
