BLC cover

BLC is a volumetric lobe pump for air particularly suitable for pressure or low vacuum.

The two trilobe rotors rotate inside the body with minimal clearances, synchronized by an oil-fitted phase gear. The non-dragging segment seals ensure maximum efficiency and longevity.

Focus points
  1. Labyrinth seals with segments and lip seal on the shaft prevent oil leakage
  2. Oversized rotor shafts
  3. Noise reduction system integrated into the body
  4. G1/2'' hole for thermostat
  5. Passage sections designed to minimize pressure losses and heating

Primary valve in carbon steel

Primary valve in carbon steel

Primary valves are designed to be welded on top of the vacuum truck tank, at the point where the vacuum/pressure line begins. They feature an integrated overflow system with a stainless steel float ball. When the tank reaches the maximum fill level, the valve prevents liquid from entering the vacuum line and reaching the pump.

Additionally, they are equipped with the following accessories: removable cover, threaded coupling for pressure relief/vacuum adjustment valve, pressure gauges, ventilation system, and cyclone valve discharge.

Cyclone valve in carbon steel

Cyclone valve in carbon steel

Cyclone valves are designed to be installed in the vacuum/pressure line between the pump and the tank.

Cyclone valves prevent external liquid or solid parts that could bypass the primary valves from entering the pump.

The cyclone consists of a vertical cylinder with a conical bottom. The flow enters the separator body tangentially through the inlet; the mixture of solids and liquids begins to spin, and the denser materials are separated from the fluid due to this descending flow, as a result of centrifugal force, and can be collected in the lower compartment. As the mixture descends along the cone, a "vortex effect" is created at the center. This process generates a vortex in the center of the cone through which the lighter flow rises.
