» DIAPHRAGM DOSING PUMPS
Ideal when accuracy and repeatability is required in the dosage. They have a "Sandwich Type" diaphragm design.
Zero Leak pumps, ideal when high levels of safety are required.
Triplex Process Pumps, for high pressures, the main applications are dosing of oil.
A line of plunger and hydraulic double diaphragm metering pumps designed according to the API 675 standards.
The flexibility of using different materials in contact with the process fluid makes possible to then satisfy a wide range of dosing and mixing applications.
The compliance with ATEX directive makes SEKO pumps suitable for being installed even in classified areas.

MECANISMS:
- Positive return type in different sizes
- Internal worm gearbox, oil bath lubricated with low noise emissions
- Rotating parts on bearings to minimize power consumption
- Each mechanism comes complete with an internal gearbox; pumps with different speeds (strokes/min) can therefore be joined to form multi-head pump units, allowing a greater flexibility when selecting the pumps themselves.
- Stroke adjustment with high precision can be achieved, both manually and automatically. Electrical and pneumatic servomotors designed by SEKO are available. Also an increase of turndown ratio can be achieved by frequency converter varying the speed of the electrical motor.

» CENTRIFUGAL PUMPS
Ideal for handling high volumes and medium pressures for low viscosity liquids.
There are different types of construction materials according to the fluid handled. Cast iron, stainless steel and special metals.
The fluid enters through the center of the impeller and some blades propel it towards the external part where the casing is located to direct it towards the discharge of the pump.

» PERISTALTIC PUMPS
|
|
OPERATING PRINCIPLE:
The internal workings of each pump comprise of a rotor block with solid rotating rollers. The pumping action results from alternately compressing and relaxing a specially designed high-pressure peristaltic hose between the pump housing and the pump compression rollers to create an airtight pocket. The fluid is pushed along the hose towards the discharge by the compression rollers, creating a positive displacement. The reopening hose behind the roller draws more fluid into the pump through the suction. Due to this method of operation where there is 100% hose closure at all time, the pump is on its own a non-return mechanism. This ensures excellent metering accuracy and reduces the need for additional equipment downstream.
