Fluimac Lotus L25 AODD Pump
Fluimac Lotus L25 CNC-machined air-operated double diaphragm pump for transferring highly corrosive, hazardous, or toxic chemicals.
Fluimac Lotus L25 AODD Pump
The Fluimac Lotus L25 is a pure air-operated double diaphragm (AODD) pump with a CNC-machined solid plastic block construction, rather than injection moulding, giving tighter tolerances, reduced vibration, and greater durability. It is designed for highly corrosive, hazardous, or toxic chemicals, including concentrated acids and bases, etching agents, and solvents, and is available in PTFE, Conductive PTFE, PE, Conductive PE, and Pure Polypropylene to suit applications from abrasive slurries and sludge transfer to semiconductor wafer chemical treatment.
Description
The Fluimac Lotus L25 is a pure air-operated double diaphragm (AODD) pump built from a CNC-machined solid plastic block, rather than the injection-moulded construction used in standard AODD pumps. This gives tighter tolerances, reduced vibration, and greater durability than typical moulded AODD pumps, making the L25 the larger-capacity sibling of the L15 in the Lotus range.
It is designed for highly corrosive, hazardous, or toxic chemicals, including concentrated acids and bases, etching agents, and solvents, and is offered in PTFE, Conductive PTFE, PE, Conductive PE, and Pure Polypropylene wetted-part materials. This suits applications from abrasive slurries and sludge transfer through to semiconductor wafer chemical treatment.
Key specifications include 1″ BSP fluid connections and a 1/2″ BSP air connection, a max flow rate of 110 lt/min, max air pressure of 8 bar, max delivery head of 80 m, and solids passing of up to 4 mm. The pump is ATEX rated (II 3/3 G Ex h IIB T4 Gb / II 3 D Ex h IIIB T135°C Db X) for hazardous atmospheres, and handles viscosities up to 25,000 cps.
Why Use This
Built for hazardous chemicals
Designed for highly corrosive, hazardous, or toxic fluids such as concentrated acids, bases, etching agents, and solvents.
Precision CNC construction
CNC-machined solid plastic block construction gives tighter tolerances, reduced vibration, and greater durability than standard moulded AODD pumps.
Material flexibility
Available in PTFE, Conductive PTFE, PE, Conductive PE, and Pure Polypropylene to match the fluid being handled.
Applications
- Concentrated acid and base transfer — corrosion-resistant material options for aggressive chemicals
- Etching agent and solvent handling — suited to highly corrosive or toxic process chemicals
- Abrasive slurry and sludge transfer — passes solids up to 4 mm
- Semiconductor wafer chemical treatment — Conductive PTFE and Conductive PE options for static-sensitive processes
- Hazardous atmosphere installations — ATEX rated, higher flow rate than the L15 for larger-volume transfer
