The pump head
The PMMA pump head is suitable for medium- and high-viscosity substances: its passages and valves allow the viscous product to fill the dosing chamber.
Dosing pumps · By application
Pumps for polymers
Polymers and high-viscosity products, from 8,000 up to 50,000 cPs, require pumps with a dedicated PMMA pump head and performance suited to the viscosity of the liquid. For low-viscosity liquids, up to 8,000 cPs, pumps for low-viscosity liquids are used. For details of the models, visit the series pages: AMS and T and TMS.

Why
Dosing a polymer
Fewer strokes per minute
As the viscosity of the product increases, a lower number of strokes per minute is recommended, giving the liquid time to fill the pump head.
Flow rate
The nominal flow rate is measured with water at room temperature: with viscous products it must be checked with the product being dosed.

Installation
Installation and priming
Short suction line
Pump close to the tank, with a short suction tube, without loops, and of a diameter suited to the product.
Priming
With viscous products, priming can be assisted with a 20 cc syringe applied to the purge valve.
Up to 8,000 cPs
For less viscous products, pumps for low-viscosity liquids are used.
