Cognito
Cognito is the electric diaphragm pump (EODD) by Warren Rupp — IDEX Corporation (USA), from the same manufacturer as Sandpiper (AODD air-operated diaphragm pump). Uses an electric motor instead of compressed air: retains diaphragm pump advantages (self-priming, dry-running, solid passage, sealless) but saves up to 75% energy, with the Smart Insights IoT platform. CE & ATEX certified. TKT authorized distributor in Vietnam.

Diaphragm pump electric-driven, energy-saving & smart
Cognito retains all diaphragm pump advantages while eliminating the compressed air system — significantly reducing energy consumption and adding IoT monitoring.
Up to 75% energy savings
Direct electric drive, eliminating compressed air system losses — significantly reducing energy costs vs AODD.
No air compressor required
Completely eliminates compressed air system & piping — simplifies installation, reduces maintenance and noise.
Sealless, dry-running
Sealless design: self-priming, safe dry-running, solid passage up to 9 mm, field-repairable.
Smart Insights (IoT)
Remote pump connectivity, monitoring & analysis; predictive maintenance; standard leak detection sensor.
CE & ATEX certified
Compliant with CE and ATEX — suitable for hazardous area zones.
Same manufacturer as Sandpiper
Manufactured by Warren Rupp (IDEX, USA) — same brand as Sandpiper AODD pumps; TKT authorized distributor.
Select correctly electric diaphragm pump
Depending on flow rate, fluid and monitoring requirements — select the appropriate port size, material and IoT configuration.

Electric diaphragm pump new generation
Cognito is the electric diaphragm pump (EODD) line from Warren Rupp — a company within the IDEX (USA), same manufacturer as the air-operated diaphragm pump Sandpiper. Warren Rupp has consolidated the former Sandpiper EODD line under the Cognito brand.
Cognito uses an electric motor + gearbox to drive the diaphragm, retaining diaphragm pump advantages (self-priming, dry running, solid particle passage, sealless) but saves up to 75% energy compared to AODD and integrates an IoT platform Smart Insights. CE & ATEX certified. TKT is the authorized distributor of Sandpiper / Warren Rupp in Vietnam.
TKT supplies Cognito electric diaphragm pumps genuine, with technical consultation on port/size selection, materials & IoT configuration based on flow rate/head and fluid type, installation, commissioning, and manufacturer warranty.
