Pneumatic pumps

The full ﬂow pneumatic pumps for pumping wells manufactured by DIMACO allow operation without any need for external controls or sensors.

The pumps are in fact able to internally control the ﬂuid level, starting and stopping according to it, without timers, electrical connections, immersed sensors or anything else.

They are recommended for working in the presence of solids in high quantities in highly corrosive environments.

The TF series pumps are ideal for installation in remediation sites or MSW landﬁlls and have demonstrated their reliability and robustness over the years in the hundreds of sites where they are installed.

The materials used for the construction of TF-TOP DIMACO pumps are suitable for pumping hydrocarbons, solvents, other corrosive supernatants and TF-BOTTOM for leachate and DNAPL. For some speciﬁc applications, they can have customized components and accessories, for better performance and durability.

The TF series pumps are designed and built to operate in potentially explosive atmospheres and in contact with aggressive substances.

The main applications for which they are used are: the remediation of contaminated aquifers and the recovery of leachate from MSW landfills.

For specific projects the pumps can be customized in terms of accessories and choice of materials.

CONFIGURATIONS

The pumps are available in two Top and Bottom configurations with fluid inlet respectively from above or below, according to the specific needs of the customer. The Top versions can be equipped of active Skimmers for the recovery of the supernatant product only: if the groundwater excursions are high, the pump can be equipped with skimmer (making it into an active skimmer) with a water evacuation system from the bottom, to recover supernatant only.

Top Configuration

The “TOP” configuration, thanks to the introduction of fluid in the body from above it is particularly suitable for the recovery of supernatant product (LNAPL).

Bottom Configuration

In the “BOTTOM” conﬁguration, the entry of the ﬂuid into the pump body from the bottom allows the recovery of heavy product (DNAPL) and allows obtaining a higher ﬂow rate.

Active skimmer

This system is used for the recovery of only the supernatant product being able to follow the movements of the aquifer thanks to the presence of the floating float with calibrated specific weight.
