1. Applications

1). 500D pump has 1/8" NPT inlet and outlet ports for rapid, low-restriction filling and dispensing and easy connection in process and pilot-plant plumbing.
2). Integral button-style pressure transducer in cylinder cap assures excellent stability and repeatability.
3). Rugged single-ratio drive train has auto-lubricating gears to assure long life and low maintenance.
4). Each Isco D-Series syringe pump is bench tested at the factory. All pumps are CE compliant and certified to UL 3101 and EN 61010-1 standards.
5). Cylinder wash system protects the seals from deposits.
6). Exclusive "Smart Key" controller. All Isco D-series pumps use the same controller that can operate any three pump modules, either independently or together. Operating modes include:
- Single pump independent constant flow or pressure
- Single pump flow - or pressure - ramp programming
- Single pump dispensing
- Dual pump continuous constant flow or pressure
- Dual pump concentration gradients
- Three-pump configured systems
7). RS-232 serial interface for computer control or monitoring of operating parameters.
8). Redundant safety is designed in. All D-Series pumps have mechanical and electrical fail-safes, in addition to the factory default or user-set limits.
9). Corrosion resistance. Nitronic 50 - the standard material for cylinders, pistons, and caps - is an austenitic stainless steel with outstanding strength and corrosion resistance.
10).Standard seals are heavy-duty, graphite-impregnated , providing very long life under harsh operating conditions.
