S300 plunger, hydraulic diaphragm and mechanical diaphragm pumps

Operating capacities from 0.9 to 10,000 litres/hour at 3 to 400 bar

Thanks to their unique, patented design, the great success and acceptance of the S300 series of dosing pumps is in part due to their innovation and part to their substantial engineering. They take metering pumps to the very highest levels of engineering and performance.

The concept of the range is to offer the simplicity of spring return or the greater accuracy of positive displacement - within the three basic configurations of plunger design, hydraulic diaphragm and mechanical diaphragm.

With such a large range of models and options, the Signal S300 provides a dosing capability at extra high back pressures or at high temperatures - molten sulphur, for example. Some pumps in the range give compliance with API 675 and others with the ATEX requirements. All can be fitted with pneumatic or electronic servos which accept 4-20 mA inputs to ensure that the pump is fully controllable.

Multi-headed options enable a single motor to run several pumps together.
