High precision pumps in a coated steel case with a detachable LCD controller and programming unit.
All relevant parameters, e.g. volume, flow-rate and flow direction, are set via the key-pad on the control unit, which can be used remotely from the pump. The key-pad has 3 function- and 2 hot-keys, plus an analogue encoder wheel for fast data entry, enabling intuitive adjustment of the set values. The back-lit LCD shows both set and actual volumes, flow-rate, and other functions. A choice of units of volume, flow-rate and specific weight can be pre-programmed, e.g. µl, ml, mg, g, µl/s, ml/m. This has a RS232 port and can be used with the FREE CAT Labcontrol for Windows software giving flexible options for multistep programs. TTL inputs and analogue control inputs are also standard. Available with a built in rinse port pump to ensure clean fluid paths. |

This digital pump employs two independently controlled pump heads. The result is a pulse-free flow without the need for secondary pulse dampeners. Apart from separate housing chambers for pumps and PC board, this pulse-free pump features the same performance as the standard HPLH pumps. The pump has a LCD and membrane keypad interface for fast and easy numeric input of all relevant parameters e.g. volume, flow-rate, flow direction and time. When detached from the pump housing the keypad can be used as a remote controller. Wetted parts are Al2O3 and Tefzel. |

CAT Dosca pumps are also available in multi-pump tower
consisting of 2 - 9 pumps in a common housing. The configuration is implemented according to customer specifications. The unit is operated either by the built-in control panel with alphanumeric display or by PC based systems. You can start all pumps simultaneous with individual preset pumping parameters. This gives great flexibility to the user, who can set up quick experiments without first having to program Once the pump parameters have been ascertained the user can easily adopt them in a program and run the system from a computer. • Operation of every pump independent from the other pumps. • RS232/RS485 communication link. • Pump units can be interconnected • Fast communication between pumps and Process Control System. • LED function indicators at each pump. • Modular Approach for easy maintenance. • upto 400ml/min on each channel. • wetted parts Al2O3 and PVDF. • available with or without rinseports.
