Injetora de PU, dosadora, máquina de espuma: entenda os nomes usados no mercado, o que muda entre alta e baixa pressão e como escolher a máquina certa.
Portable metering
SP-15E and SP-30E portable dispensers
Portable metering with Sulpol engineering: up to 15 or 30 kg/min, 1:1 mix ratio by volume.
Overview
SP-15E and SP-30E: portable metering with Sulpol engineering.
The SP-15E and SP-30E take polyurethane metering to the point of application. They fit processes that need mobility, quick set-up and control of ratio, temperature and pressure without the structure of a fixed installation.
The circulation gear pump and the static mixing gun are manufactured by Sulpol itself. That lets us stand behind the whole assembly that meters and mixes — and keep parts and know-how under one roof.
-
Digital calibration
A calibration routine to check the mix ratio with the material in use.
-
Temperature and pressure under control
Control of the two parameters that most affect viscosity, mixing and reactivity.
-
Sulpol gear pump
Component circulation by an in-house gear pump.
-
Sulpol static mixing gun
Static mixing in the gun, also designed and built by Sulpol.

To specify with confidence
Como especificar uma dosadora de poliuretano: as perguntas que importam
Material, relação de mistura, vazão, tecnologia de mistura e integração: o roteiro para especificar uma dosadora de PU a partir da peça que você precisa produzir.
Relação de mistura 1:1 em volume ou em massa? Por que a diferença importa
Poliol e isocianato têm densidades diferentes. Entenda como converter a relação de mistura entre volume e massa e como conferir a dosagem na calibração.
Next step
Let’s assess your application.
To recommend a configuration we need to know the product, the polyurethane system, the mix ratio (by weight or by volume), the target output and the operating mode.
