MATERIALS
The GILARDONI gear pumps belong to the volumetric rotary pumps with external teeth category and they are reversible, so they can work both clockwise and anticlockwise.
CAST IRON SERIES
The pump body, the lids and the supports are made of high quality cast iron G25 made either by fusion or by bar, according to customer requirements.
GEARS AND SHAFTS
The gears and the shafts are made of carbon steel ETG100-ETG88 with a special “TENNIFER” hardwearing and anti-seize treatment that guarantees an increased resistance of the product through time.

SEALS The seals between the coupling faces of the various elements are made with rubber O-rings.
ENDURANCE The endurance is made with self-lubricating bronze bushes removable to allow easy replacement in case of wear.
DUCTSThe suction and delivery ducts are externally threaded. On request we can install ASA flanges.
SEALS The shaft seal is guaranteed by a reversible mechanical seal in graphite / steel with Viton o-Ring. We can also install reversible mechanical seals with PTFE gaskets and seals with static and rotary rings in special material such as tungsten carbide and / or silicon carbide. On request the pumps can also be provided with packing seal.
STEEL SERIES
The pump body and the supports are made of stainless steel 316 fused (CF8M) or from bar.
