Abstract

Appts. for dispensing a liquid resin or resin precursor comprises a combination of a reservoir and a ram pump for transferring the liquid from the reservoir to an outlet circuit via a combination of a pulse damper and a variable flow control device. The pumped stream can be also be returned to the reservoir via a recycle loopr or vented via a branch outlet in the event of excessive outlet backpressure. Suitable for spraying coatings or injecting fillings at outputs of e.g. 0-10kg/min. at 0-20 bar of e.g. polyurethane foam into cavity walls on site to obtain foam densities of 30-80kg/m3. Appts. involving ran pumps can be lighter and more compact and hence more manoeuvrable than appts. involving rotary pumps for an equivalent output range.
