The PHD 4400 Hpsi Programmable Syringe Pump is asinglesyringeinfuse-withdraw pump equipped with all the functionsof thePHD22/2000 Programmable Model, but with a high-power steppermotortoprovide up to 200 lbs. of linear force.

Pressure and Speed

The PHD 4400 Hpsi can deliver up to 220.82 ml/min with asingle140ml syringe. Maximum pressure is dependent on syringesize.Forstainless steel syringes, see page A70.

Flexibility and Easy Programmability

Two standard infusion modes (continuous or volume dispense)

Internal programmable pump control in all models

In Program Mode, complex infuse and withdraw applicationscanbeeasily created, stored in the pumps nonvolatile memoryandrecalledfor later use.

Features

Universal Input Power Supply: No need to change AClineswitches,fuses, or wires.

Nonvolatile Memory: Stores all operational dataandprogramsequences.

Stall Detection: An optical detector verifies motormovement.Stallsdue to jamming or excessive back pressure arereported.

Visual/Audible Alarms

Power-Up Options: Powers-up in Standby orRunningModeafter power interruption.

RS-232 Connections: Allowsdaisy-chainingofmultiple pumps for remote control. Also allows forscaleandprinter connections.

TTL Connections: Allows for synchronizingpumpwithexternal devices, controlling an external valve,changingdirectionof travel, etc.

Modes of Operation

Pump Runs continuously in the infuse or refilldirectionsuntilstopped.

Volume Runs until specified volume has been pumped or refilled.

Program Pump operates according to specifiedsequenceofinstructions. (Note: All modes

interact with Autofill feature.)
