What’s Included
- 1× Medfusion Syringe Pump Model 3500 with Software Version 6
Product Description
Fully refurbished, biomed tested and calibrated by United Infusion, and backed by a 1-year warranty, the Medfusion 3500 V6 supports controlled syringe-based infusion across critical care, anesthesia, neonatal, pediatric, and other clinician-supervised healthcare settings.
PharmGuard Medication Safety Software allows facilities to create custom pump Configurations using PharmGuard Toolbox 2 Version 3 or higher. A Configuration may contain global settings, up to 16 Profiles, library definitions, Drug Programs, syringe definitions, and programmable hard and soft infusion limits. Each Profile may contain up to eight Categories, with up to 36 Drug Programs per Category.
The pump supports Medfusion Standard Syringes Series 2 and compatible PharmGuard Supported Syringes (PSS) Series 2 in sizes from approximately 1–60 mL, depending on the syringe models loaded in the pump's Configuration. The operator selects and confirms the syringe model and verifies the detected syringe size before beginning delivery.
FlowSentry pressure monitoring provides pressure trending, rapid occlusion detection, and post-occlusion bolus reduction. FlowSentry availability depends on syringe model, size, and infusion rate and may automatically disable at higher flow rates.

Refurbishing Process
At United Infusion, we follow a comprehensive refurbishing process for infusion pumps to help ensure they operate safely and reliably. This process follows manufacturer guidelines and sanitation standards to meet high quality expectations.
Below are the key steps of our refurbishing process:
2. Disassembly
The pump is carefully disassembled to access internal components, including the motor, gears, tubing pathways, and electronics. All parts are handled with care to avoid added damage.
3. Cleaning & Sanitization
Appropriate disinfectants are used to thoroughly clean all parts and remove residual fluids, blood, or debris. This step follows sanitation standards to help ensure the device is free from contaminants.
4. Component Inspection & Replacement
Individual parts, including the motor, battery, display screen, buttons, and connectors, are inspected for wear, damage, or malfunction. Worn or damaged components are replaced with manufacturer-approved parts.
5. Calibration & Software Update
The pump is adjusted to support accurate fluid delivery rates using standardized testing methods, and calibration is verified against manufacturer specifications. The latest compatible software version is then installed to improve functionality.
6. Testing, Reassembly & Final Check
The pump goes through functional testing, including alarms, flow rate accuracy, occlusion detection, and bolus delivery. It is then reassembled, connections are checked, and a final visual and functional inspection is completed to confirm it meets safety standards and customer requirements.
"We needed our syringe pumps serviced for scheduled maintenance to continue to provide safe care. In the past, we had to send them off with a 6 weeks turn around time. Then we found United Infusion. 30 min down the road, 24 hr turn around and 30 minutes down the road. We are extremely grateful!!!"
