Continuous Flow Pumps

The most popular OPAM Syringe Pump is the continuous low pump model, with two pump heads, which is capable to deliver two liquids simultaneously or successively.

All OPAM Syringe Pumps have one or two pump heads or even four ones. They can be used as well as Single or as Dual Head pumps. In all models complete electronics and software is assembled and the pumps are ready for further updating.

The programming of pumps and possible additional valves is easy and straightforward using the local keyboard or a computer via RS232 or USB connection.

External Signal Controlled Pumping

Many laboratory equipment have an output connection to use external devices. OPAM Syringe pumps can also be controlled by these output signals. Typically these are standardized direct current voltages or currents.

Voltage control

OPAM Syringe Pump accepts 0 ... 5 V or 0 ... 10 V control signals. The pumping speed is linearly dependent on the voltage and the maximum speed is obtained at 5 V (or 10 V) and the pump stops at 0 V.

Single Shot Pumps

These pumps are the simplest models of OPAM Syringe Pumps. There is always only one syringe or a set of single syringes in the pump head. These pumps will deliver liquid at the constant speed as long as there is liquid left it the syringe.

Semiautomatic Pumps

These pumps are equipped with a three way valve, which will direct the liquid low during the filling and emptying period of the syringe. These pumps are suitable for applications, where a desired volume is needed to fill bottles or other vessels, also successively.

Standard control current signal is 4 ... 20 mA. OPAM Syringe Pump accepts also this signal. The pumping speed is linearly dependent on the current and the maximum speed is obtained at 20 mA and the pump stops at 4 mA.
