Standard Infuse/Withdraw PHD 4400 Hpsi Programmable Syringe Pumps
The Harvard PHD 4400 Hpsi is a single syringe version of our precision PHD syringe pump series with a higher pressure motor. It provides 200 pounds of linear pumping force for high pressure applications. It can hold syringes from 0.5 microliters to 140 milliliters provide a wide flow rate range from 0.0001 µl/hour up to 220.82 ml/minute. It is programmable from the keypad providing exceptional versatility in a single pump. It is also available in a remote version where the control box and pumping mechanism are separated by a 9.1 meter (30 foot) cable.
pumping force across a wide flow rate range
• Accurate and smooth flow
• Ideally suited for stainless steel syringes
• Easy-to-use interface
• Control from your PC via serial
• 2 year warranty
The PHD 4400 Hpsi Programmable Syringe Pump is a single syringe infuse-withdraw pump equipped with all the functions of the PHD 22/2000 Programmable Model, but with a high-power stepper motor to provide up to 200 lbs. of linear force.
Pressure and Speed
The PHD 4400 Hpsi can deliver up to 220.82 ml/min with a single 140 ml syringe. Maximum pressure is dependent on syringe size. For stainless steel syringes.
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 applications can be easily created, stored in the pumps nonvolatile memory and recalled for later use.
• Autofill Mode provides continuous delivery when the pump is used in conjunction with either a standard or high pressure valve box and a fluid reservoir.
Ease of Use
Setting the pump is quick and easy. Input the diameter of the syringe or use the internal Syringe Lookup Table to automatically input the syringe diameter based on the syringe manufacturer and size. Select a mode (continuous delivery or volume dispense) and a rate and you are ready to go.
Universal Input Power Supply: No need to change AC line switches, fuses, or wires.
Nonvolatile Memory: Stores all operational data and program sequences.
Stall Detection: An optical detector verifies motor movement. Stalls due to jamming or excessive back pressure are reported.
Power-Up Options: Powers-up in Standby or Running Mode after power interruption.
RS-232 Connections: Allows daisy-chaining of multiple pumps for remote control. Also allows for scale and printer connections.
TTL Connections: Allows for synchronizing pump with external devices, controlling an external valve, changing direction of travel, etc.
Modes of Operation
Pump Runs continuously in the infuse or refill directions until stopped.
Volume Runs until specified volume has been pumped or refilled.
Program Pump operates according to specified sequence of instructions. (Note: All modes interact with Autofill feature.)
