How do you adjust a metering pump?
How do you adjust a metering pump?
Since a metering pumps is usually a positive displacement pump there are two possible ways of controlling the flow capacity. The first one is by adjusting the volume of liquid displaced per stroke of the pump and the second is by adjusting the speed of the strokes.
How do you adjust a pulsafeeder pump?
While pump is running, turn adjustment knob counterclockwise. Run with valve open until a solid stream of fluid comes out of the bypass tubing with no air bubbles. Close air bleed valve by turning adjustment screw clockwise. Chemical should reach the pump head after a few minutes of operation.
How does a pulsafeeder pump work?
A diaphragm metering pump moves liquid in a specific time period and provide an accurate volumetric flow rate. Metering refers to the delivery of fluids in precise flow rates. The metering pump drives chemicals, liquids and other solutions, generally for water treatment plants.
How do you bleed a dosing pump?
To bleed these models, whilst the pump is running, you simply unscrew the cap until you get a dribble of water coming out of the back of the pump. Now using the shut off valve fitted on the PRESSURE side of the pump, close it and open it sharply 2-3 times.
How does a metering pump work?
A metering pump moves a precise volume of liquid in a specified time period providing an accurate volumetric flow rate. Most metering pumps have a pump head and a motor. The liquid being pumped goes through the pump head, entering through an inlet line and leaving through an outlet line.
Which pump is commonly used for metering pump?
|Pump type||Minimum flow rate||Advantages|
|Bellows||6||Pumps liquids or gases|
|Peristaltic||170||Noncontaminating; wide variety of pump materials available|
|Piston||0.016||Highest pressure and accuracy|
What does a diaphragm pump do?
Diaphragm Pumps deliver a hermetic seal between the drive mechanism and the compression chamber, allowing the pump to transfer, compress, and evacuate the medium without a lubricant. An elastomeric diaphragm can be used as a versatile dynamic seal that removes many of the limitations found with other sealing methods.
How do you remove air from a pump?
Follow these instructions to remove air from your pump installation.
- Turn off pump.
- Remove shower head from hose.
- Let hose hang into bath or shower tray.
- Turn the temperature to full cold.
- Turn the shower on and run for 5 minutes.
- Turn the temperature to full hot and run for a further 5 minutes.
- Turn off the shower.
How does the Pulsatron series 100 metering pump work?
* NOTE: For accurate volume output, pump must be calibrated under all operating conditions. INTRODUCTION Series 100/150 are diaphragm-type metering pumps. A fluid is pumped from a chemical storage tank to the point of injection by the pulsing action of the diaphragm.
How does the solenoid on a Pulsatron work?
The thermally protected solenoid protects the pump from seizing up in extreme heat conditions with an automatic reset feature allowing the pump to resume operation up on cool-down. All PULSAtrons are tested and rated under hot conditions guaranteeing that the flow and pressure ratings meet the specifications.
What do I need to know about Pulsatron Series E Plus?
The Pulsation Series E Plus offers manual control over stroke length and stroke rate as standard with the option to choose between 4-20mA and external pace inputs for automatic control.
What’s the maximum capacity of a Pulsatron pump?
Metering performance is reproducible to within ± 2% of maximum capacity. Over 25 years of excellence, PULSAtron pumps carry agency approvals of ETL, ETL Sanitation, CE and NSF 61 (PVDF material and PVC Degassing Head models). How did you hear about us?
