Preciflow

The development of these peristaltic pumps was based on long time experience of laboratory.They have been continuesly improved. The result is a practical, precise and reliable laboratory pump which is one of the most compact in its class. The for pumps cover a flow rate range from 0.01 ml/h to 10000 ml/h.

Description

• digital set point can be adjusted over three powers of magnitude
• remote controls
• greatly extended tubing life and quite no pulsation
• plug-in power supply for increased safety
• very economic in use while using low cost tubing without stoppers

Interesting construction features

• Instead of small rollers, which are used by most pump producers, the pump has bearings of a larger diameter with glass beads. This reduces pulsations, friction and mechanical strain on the tubing leading to better pump performance.
• The bearings glide over the tubing so gently, that unlike other pumps, it is unnecessary to prevent movement of the tubing by a special fixation. In this manner the life time of the tubing is considerably increased.
• The pressure on the tubing is delivered individually through an off-center lever and spring made of stainless steel. This assures that a minimal pressure is applied to the tubing which still guarantees good functioning of the pump without unnecessary deformation of the tubing.
• The spring also reduces the liquid pressure to approx. 1 bar. This is useful when for any reason the line is blocked.
• The asymmetric pump head reduces pulsation.
• A high quality stepping motor together with integrated microprocessor electronics assure a high precision of flow rate with no inertia while turning the pump on and off.
• The pump head is made from hard, chemically stable epoxide.
• The pump dimensions have been minimized. Therefore the PRECIFLOW pump is considerably smaller than other products of similar performance. The pump is easy to use and saves space in the laboratory.
• Remote control and the possibility of flow integration with the INTEGRATOR increases the scope of use of the pump in automatically controlled systems (eg. fermentation, chemical synthesis, fraction collection, etc.)
• high quality/price ratio, low use-costs, easy handling

Remote control

Remote control of the speed by external voltage 0-10 V (0-20 or 4-20 mA); ON/OFF control by external contact or 3-12 V voltage; compatible with other LAMBDA instruments (Pump-flow integrator and Omnicoll fraction collector); RS 485 as option. It can be connected to a controller, for example for pH control with an acid, or to a computer with the programs Siam or PNet.
