Euterpe Single-Use-Pump's (SUP) all consist of:

The Euterpe Air-Operated-Diaphragm-Positive-Displacement (AODPD) Single-Use-Pump (SUP) cell’s consist of a housing integrating a valve body, a dome, the diaphragm, and the fluid conveying hoses – all supplied pre-sterilized in dual film bags.

The basics in operation is copied from the human heart functionality:

• Cardiac Output (CO) = total pumped volume, SUP capacity, ml/min (CO = BpM x SV)
• Beats-per-Minute (BpM) = ranging 0 - 30 BpM, SUP diameter/stroke/volume depending
• Stroke Volume (SV) = programmable from 10 - 100% of SUP cell specification

Physical features

• No expensive housing materials for traditional steam cleaning requirements
• No mechanical axle seals
• No mechanical rotating parts such as electrical motor, coupling or gears
• No moving ball valves, only passive cross-slit silicone valves
• All simple single-use plastic parts – contamination eliminated
• Low weight and compact design gives OEM manufactures new freedom to design equipment
• Measures accurately pumped volume, a true Positive Displacement pump – no in-line flow-sensor is needed
• All pumps offer infinite turn-down, turn-up scale of 1:5.000

Operating features

• Volumetric operation precision better than 1% - without any extra flow sensor
• Volume per stroke depending on pump size - no minimum volume exist
• Zero spallation / shedding of membrane materials - shear never introduced
• Self-priming from 2 meter suction height
• Standard fluid pressure 1 bar - higher pressure like 3-5 Bar require customized body
• No need for calibration - build in artificial inteligence in Drive Unit
• Pump any fluid - any mixture of liquid and gases
• Dry running for extended periods
• Self-emptying, drain on inlet and purge on outlet as the pump will convey gas as well
• Single-use, disposable wetted parts eliminate cleaning issues – just un-pack and exchange without any tools needed
• Very gently operation with no rotating or rubbing parts - no shear introduced between used polymeric materials parts creating nano size polluting particles
• Working pressure as much as 5 Bar on special models makes the SUP suitable for connection with filtration devices
• Two or four pumps able to operate fully controlled and in parallel connected to Atropos-2
• Two pumps able to operate fully controlled in parallel when connected to Atropos-1

Programming features (on Atropos)

• Select the continuous volume you want to pump – (well, according to pump size)
• Select the total volume you want to pump
• Select the time you want the pump to operate
• Real-time information about pumping, pumped volume and velocity

Maintenance features

• No tools needed replacing the SUP cell - takes only one minute !
• No lubrication needed
• No need to strip down pump for cleaning
• Longevity - tested to last 1 million cycles at 75% CO

Installation features

• Single-Use-Pump cell may easily be part of an all sterile process package
• No tooling needed for Single-Use-Pump cell replacement - one minute operation

Data collection features of Atropos Drive Unit

• On-line operation pressure measured by build-in pressure sensor
• On-line Mass-Flow-Control / metering, the pump measures the volume pumped with better than 1% accuracy - without external flow sensors!
• Data acquisition, data logging

Communication features of Atropos drive unit

• Single-Use-Pump cell's need connection to Atropos Drive Unit (requires only pressurized air, vacuum and 24 VDC electrical power)
• TCP/IP bus connection or Wi-Fi connection
• All Euterpe kids are stand-alone and share the same family of Atropos Drive Unit's
• Atropos software up-gradable
• Atropos units facilitate a webhost, which allow the user to access Atropos via Wi-Fi as well as via IP/TCP from many devices via Ethernet, USB connection (for data export), OPC communication
• Access Atropos via build-in touch sensitive display or connect via Wi-Fi a PAD, Smartphone or PC

Not designed for:

• Viscosity higher than 10,000 centiStoke
• Very abrasive materials for a long time
