Overview; Application And Product Identification; Operational Principle Of Mechanical Diaphragm Pump - Seko MSA Série Manuel D'installation

1. Overview

The metering pump is a reciprocating positive displacement pump; basic components are: the
motor, the gearbox, the mechanism, the stroke length adjustment and the liquid end (pump head)
Safety instruction
WARNING
Exceeding the maximum allowed operating pressure must be prevented
(e.g. by using a pressure relief valve)
Before starting to work on the metering pump verify carefully the following:
- The drive is disconnected from the power source
- Parts such as pump head and piping are depressurized
- Parts in contact with aggressive substances are washed before handling
- Personnel protection is carried out according to local regulations

1.1 Application and product identification

Metering pump is a process component capable to transfer defined volumes of liquid with high
accuracy; moreover it is possible to vary the flow rate by acting on integral devices.
To obtain the best performances, select the pump considering the duty required and the
compatibility of the construction materials of the contact parts.
Before using a pump for a duty different from the original one, please contact us
for information.
Actual dimension of product identification 53x35mm

1.2 Operational principle of mechanical diaphragm pump

Mechanism is the device that permits to transform the electric motor rotary movement into
reciprocating movement by gearbox. The reciprocating movement draws membrane, making
the volume of pump chamber change to push the ball up and down to form vacuum adso
rption and squeezing for fluid transfer. The adjustment of flow rate is realized by regulating
the stroke length.
