NRP refrigerant pumps
WITT NRP, the new standard for CO2 pump systems up to 63 bar
WITT NRP was developed with years of experience for reliable operation with the natural refrigerant CO2 (R744) at up to 63 bar shut-off pressure.
Outstanding performance
The new hydraulic design and no need for a motor can improves efficiency. Almost the entire volume flow is available for your system, as the NRP requires only a very small motor cooling line. No
additional QMIN and/or overflow line is needed. The wide permitted frequency range between 20 Hz and 60Hz allows you to operate the NRP constantly at the optimum
operating point.
Easy installation
A bracket around the center of gravity of the pump facilitates installation, the round shape makes the NRP is easy to isolate.
Replacement for almost any type of refrigerant pump
The connections can be adapted to the situation of the installation. This also makes it possible to replace other brands of pumps.
Maintenance-free design
The NRP sturdy design allows maintenance-free operation even with the presence of dirt particles, refrigerating oils, gaseous refrigerant and sudden pressure drops.
If the system should nevertheless require service, the entire inner part of the pump can be removed from the housing, so the housing can remain in the system.
Wide application range:
2 Models, each up to a maximum of 4 stages.
Choose between the models NRP-W x/5 and NRP -W x/12, each with 1 to 4 impellers.
