Designed for precision dispensing of drugs, colorants, and food additives, this pump's single crankshaft drives two fluid-displacing pistons, two cylinders, and has no port valves.
Crankshaft speed and position control provide accurate volume delivery from zero to maximum speed. Detachable manifold provides either independent or connected cylinder channels. Spring-loaded lip seals between pistons and cylinders, combined with optically flat mating surfaces between cylinder heads and port plates, result in zero leakage and fluid "slip by." Other ad-vantages include:
- Near-zero dead volume
- Accuracy at all speeds
- Infinite range from zero to maximum rated capacity, (mu)(liter)/min to (liter)/min
- Low pulsation
- Built-in over-pressure protection
- Valveless design
- Run dry capability
- Programmable remote control capability
- Low to >100 psi capacity
