MCP & NRP Series Inert Dispensing Pumps
Solenoid Operated, Dispensed Volumes From 1 to 800 µ
DESCRIPTION
Model MCP & NRP dispensing pumps have inert wetted parts and accurately dispense liquid media over an adjustable range of 1 to 800 micro liters.
The pumps utilize a solenoid operated piston with a spring return. The MCP-10 type pump is basically a two-way inert valve with one port plugged. The pumping function is like that of an eye dropper. The MCP-50 and the NRP type pump have opposing duck bill type check valves at the pump inlet and outlet that work with the piston movement for pumping action. The piston stroke can be field adjusted or factory set to deliver a prescribed volume with each solenoid actuation. The process media is isolated from the metal solenoid parts by an inert diaphragm.

OPERATING NOTES, Models MCP-50, NRP-300,500,800
1)The pump duck bill type check valves open at very low differential presssure so the pump outlet must be mounted above the fluid reservoir to prevent siphoning.
2)The pump should be mounted horizontally with the base side down. 3)When the dispense volume is less than 250µl, purging air bubbles is more difficult. It is therefore advisable to prime the pump at max delivery before setting the desired dispense volume.
3)Consult factory for effect of media temperature on output.
