12V DC AUTOMATIC SUBMERSIBLE PUMP FOR THE RECOVERY OF LNAPL

12 V automatic and submersible pump for the recovery of LNAPL.

HYDRO/P1A is a device for the recovery of LNAPL, equipped with elements dedicated to the recognition of air/water/product and stop and automatic restart systems. The device works with AC 220V electrical control panel that controls the pick-up equipment, which operates in DC 12V. The equipment is provided with a maximum delivery height of 5 bars (reference data: flow rate of 2,0 l/min with 1 bars delivery height). The control panel is normally made in IP55 version for outdoor installation; if required, it can be made in an explosion-proof Exd version. The components of the recognition system of air/water/product (floaters) form an intrinsically safe circuit Exia (double level floater Exia, driven by an isolated dual channel barrier Exia) with a protection up to two independent failures in the system. The device has a maximum delivery height of 55 metres and it is provided as standard with a 20 metres cable that is equipped with two interchangeable metal mesh filters.

  • Lenght: 430 mm

  • Body pump: acciaio inox AISI 304

  • Max flow rate: 2 L/min

  • Max delivery rate: 55 m

  • Cable diameter: 10 mm

PASSIVE SKIMMER

Submersible trap specific for the recovery of LNAPL.

The passive skimmer is a submersible trap specific for the recovery of LNAPL. The system is provided with a floating mechanism suitable to the fluctuations of the aquifer, which allows the entry of LNAPL, and a collecting tank for the product itself. The passive skimmer consists of a reamer (skimmer) dedicated to the oil / water separation, equipped with a float for the recovery with gravity. Another constituent part of the passive skimmer system is the collecting tank, located below the skimmer, useful to trap the floating product. The recovery of product happens with gravity; therefore, the effectiveness depends on the combination of viscosity and initial thickness. In the best conditions of viscosity and initial thickness, the passive skimmer is able to visibly reduce the layer of floating product. The passive skimmer must be manually extracted and emptied from the well. The total length of the passive skimmer is 180 cm and, of these, 40.5 cm constitute the effective skimming travel.

  • Materials: fiberglass, steel, Viton, tygon

  • External diameter: 60 mm

  • Specific gravity of extracted product: ≤ 0,85 g/cm3

  • Kinematic viscosity: 1-1000 cSt

  • Initial thickness of the product: from 20 mm to 70 mm (depending on the viscosity)

ACTIVE SKIMMER

Submersible pump for the recovery of LNAPL

The active skimmer is a submersible pump pneumatically driven which is specific for the recovery of LNAPL. The pump is equipped with a floating mechanism that allows the entry of only LNAPL, if it is present. The active skimmer consists of a reamer (skimmer) devoted to the separation of water/oil, equipped with a floater for the recovery with gravity. Another fundamental part of the active skimmer system is a pumping unit situated below the skimmer and useful to send the product to the superficie through ON/OFF cycles of compressed air (total fluid pumps). The recovery of product happens with gravity, indeed its efficacy depends on the combination of viscosity and initial thickness. Under the best conditions of viscosity and initial thickness, the active skimmer is able to visibly reduce the layer of LNAPL. The total length of the active skimmer is 180 cm, of which, 40,5 cm constitute the useful floating part.

  • Materials: fiberglass, steel, Viton, tygon

  • External diameter: 48 mm

  • Specific gravity of extracted product: ≤ 0,85 g/cm3

  • Kinematic viscosity: 1-1000 cSt

  • Initial thickness of the product: from 20 mm to 70 mm (depending on the viscosity)
