Improved displacement resolution on this new model gives finer control over motor movement. Coupled to our patented servo circuit, this means the 1000D can deliver excellent flow accuracy without the need for external flow meters. You get low-flow precision at any pressure, plus the high speed smoothness and power of a DC motor.

The 1000D features 1/4" NPT fittings on inlet and outlet ports for less restriction in filling with viscous materials and for easy connection in pilot plant and other common applications. It also has a special piston wash gland that lets you rinse the cylinder wall behind the primary seal, reducing or eliminating corrosive or abrasive effects of the fluid being dispensed. The result is a longer lasting pump with lower maintenance costs.Standard Features

• 1000D's piston wash gland reduces effects of abrasive particles on seals and cylinder
• Integral button-style pressure transducer in cylinder cap assures excellent stability and repeatability.
• Rugged single-ratio drive train has auto-lubricating gears to assure long life and low maintenance.
• 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.
• Cylinder wash system protects the seals from deposits.
• 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
• RS-232 serial interface for computer control or monitoring of operating parameters.
• 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.
• Corrosion resistance. Nitronic 50 - the standard material for cylinders, pistons, and caps - is an austenitic stainless steel with outstanding strength and corrosion resistance.
• Standard seals are heavy-duty, graphite-impregnated Teflon, providing very long life under harsh operating conditions.

Applications

• Precision fluid addition in research and manufacturing processes
• Reactant feed in chemical process development, catalyst evaluation, plastic formulation
• Accurate metering of liquefied gases

Options and Accessories

• Hastelloy or Titanium construction
• Temperature control jacket (cylinder cooling for filling with liquefied gas; thermal stabilization for ultra-low flow rates)
• High-temperature pressure transducers (for operation with pump cylinder heated up to 200°C maximum)
• High-precision pressure transducers (0.1% linear accuracy)
• Drivers for LabVIEW graphical programming software from National Instruments
• Alternate seals optimized for special applications: virgin Teflon for corrosive fluids, heavy duty reinforced for slurries and viscous fluids, high temperature, low temperature, and UHMW polyethylene. Choice of seals can be ordered factory-installed.
