What Types of Chemical Pumps Does GemmeCotti Manufacture?

Updated

GemmeCotti designs and manufactures chemical pumps for acids, aggressive and corrosive liquids, and its range covers magnetic drive centrifugal, turbine, rotary vane, and self-priming pumps, plus mechanical seal, ATEX, vertical, air-operated double diaphragm, and portable pumps. The company has been building these pumps since 1992 and assembles them with components from Italian suppliers. The type you need depends mainly on the required flow rate (Q), head (H), and whether the liquid or environment demands an explosion-proof (ATEX) configuration.

Magnetic drive pumps

Magnetic drive (mag drive) pumps transmit torque through magnets rather than a shaft seal, which removes the most common leak path when handling acids and corrosive liquids. GemmeCotti lists four mag drive families:

Pump type Max flow (Q) Max head (H)
Mag drive centrifugal pumps 130 m³/h 48 mlc
Mag drive turbine pumps 9 m³/h 50 mlc
Mag drive rotary vane pumps 2,100 l/h 13 bar
Self-priming mag drive pumps 25 m³/h 22 mlc
  • Centrifugal: the highest flow in the range, suited to transferring larger volumes at moderate head.
  • Turbine: lower flow but head up to 50 mlc, useful where pressure matters more than volume.
  • Rotary vane: the only type rated in bar (13 bar) rather than mlc, so it fits higher-pressure duties at low flow.
  • Self-priming: can lift liquid without a flooded suction line, which helps when the pump sits above the tank.

Sealed, ATEX, and vertical pumps

  • Mechanical seal pumps: Q max 130 m³/h, H max 48 mlc — the same envelope as the centrifugal mag drive line, for duties where a mechanical seal design is preferred.
  • ATEX pumps: Q max 130 m³/h, H max 48 mlc — for installations requiring explosion-proof equipment.
  • Vertical pumps: Q max 130 m³/h, H max 48 mlc — a configuration choice for sump or tank-mounted service.

Diaphragm and portable pumps

  • Air-operated double diaphragm pumps: Q max 310 l/h, H max 80 mlc — the highest head among the non-vane options, driven by compressed air.
  • Portable pumps: Q max 13 m³/h, H max 14 mlc — small, mobile units for lower-flow tasks.

Supporting products

Beyond pumps, the site lists electric and pneumatic mixers, drum pumps, self-priming dosing pumps, and accessories. These let you complete a transfer or dosing setup around the pump rather than sourcing fittings separately.

Matching a pump to your application

GemmeCotti names these application areas: chemical industry, galvanic industry, PCB industries, water treatment, air treatments, detergents, biofuel, loading/unloading tanks, oil & gas, food industry, bottling companies, pharmaceutical industry, aquariums, fertilizer production, textile industry, and refrigeration systems for data centers.

To narrow the choice, work through three questions:

  1. What flow and head do you need? Compare your duty point against the table above. If you need more than 130 m³/h, none of the listed ranges covers it; if you need high pressure at low flow, the rotary vane line (up to 13 bar) is the relevant one.
  2. Is the area classified? If yes, look at the ATEX pumps rather than a standard model.
  3. Can the suction be flooded? If not, the self-priming mag drive pump avoids priming problems.

The company also states that it customizes products for industrial and OEM processes and provides assistance throughout the purchase process, so a duty point outside the standard ranges is worth raising directly through the site's quote request rather than assumed to be unavailable.
