Asphalt / Bitumen

DESMI has a full range of different pumps and matching equipment supporting the handing of bitumen products. Including unique features suited for today’s needs and new polymer based formulations, we have the solution.

For certain applications, we can offer proven sealing options, available is also a patented zero-leakage pump with a state of the art magnetic coupling. This pump offers a total protection against spillage and vapour, which may create environmental hazards. Electrical heating is an alternative to heating by liquid or steam.

Applications tend to fall into four categories: Production (refining), distribution (terminals), hot mix (paving mixtures), and roofing (filled asphalts).  Refineries and terminals often use steel pumps, while hot mix asphalt plants use mainly cast iron pumps with heating jacketed, and either packing or mechanical seals. Roofing plants are generally pumping highly abrasive, filled asphalts for shingle manufacturing. These require special hardened parts, slower operating speeds and other means of minimizing wear. 

We are one of the world’s leading manufacturers of internal gear pumps

Reclaimed oil burner feed pumps are "Hard Fitted" - specially designed for continuous delivery to the burner. Clean oil burner feed and heat transfer pumps provide efficient positive delivery of clean oil and heat transfer liquids. Cast iron fuel pumps deliver truck unloading flow rates of 170 m³/h and include construction options based on clean and reclaimed burner fuels.
