PRINCIPLE

Marko metering / dosing pumps are reciprocating positive displacement pumps for fluids, with a Continuous adjustment of metered flow. In one compact machine, the metering pump combines the Functions.
1. Conveying
2. Measurement
3. Adjustment

OPERATING RANGE

There are various models which can metered 2 Lph To 15000 Lph Against Maximum Discharge Pressure of 1000kg/cm2 At low or high temperature.

MATERIAL OF CONSTRUCTION-(CONTACT PARTS):

• 5.5.316/S.S.304/Hastelly-B - or C/ Alloy-20/
• Polypropylene/Uhmwpe/Pyc/Ptfe/20% G.F.T.
  (Plunger or as per customer's requirement.)

FEATURES

• All rotating components are hardened and ground.
• Our Pumps are capable to dose the fluid within Accuracy +/- 1% and Turn Down Ration 10: 1.
• Easily compatible with most of the fluids.
• Steady state metering accuracy of +/- 1% of pump output.
• Single setting of stroke from 10%-100% by interlocking mechanism.
• Simplex and Multiplex arrangements of pumps available for universal use.
• Positive return of plunger and variable stroke mechanism allows linear relationship between control stroke setting and stroke length.
• Reproducibility (Repeatability) better than +/- 2.5% of set point.
• They have low NPSHR requirement.
• Stroke Adjustment 0 TO 200 SPM.
• Digital Stroke Length adjustments to achieve very high accuracy.
