About Air Operated Diaphragm Pumps
MECHANICAL DIAPHRAGM PUMPS TRANSFER THICKER FLUIDS WITH GREATER EFFICIENCY
Hunter Pumps’ mechanical diaphragm pumps are built with precision and durability in mind. These pumps, defined by their heavy-duty construction and heavy-duty gearbox coupled with versatile electric, petrol, or diesel engines, are apt for transferring wastewater, recovering oil spills, and dewatering project sites.
The mechanical diaphragm pump operates by utilising a compression chamber, with the diaphragm facilitating the movement of fluids, including challenging substances like sludge. Additionally, they can efficiently ‘run dry’ or ‘on-snore,’ ensuring fluids are moved in a safe and energy-efficient manner.
Applications of Hunter Pumps' Mechanical Diaphragm Pumps:
- Dewatering in various industries, including construction sites, ponds, excavations, and machine sumps.
- Generating pressure for spraying, washing, and filter press functions.
- Handling fluids in the abrasive slurry, oil, pharma, and gels sectors.
- Pumping shear-sensitive foodstuffs, sticky fluids, corrosive chemicals, volatile solvents, and smaller solids.
- Dosing, dispensing, and metering.
- Raw sewage and wastewater management.
- Pool maintenance and construction.
- Operations in waste treatment plants.
- Oil skimming bore desludging and oil/water separator supply.
- Pool maintenance and construction.
- Drum emptying in abattoirs and poultry processing.
KEY FEATURES OF MECHANICAL DIAPHRAGM PUMPS
Rapid Self Priming
These pumps quickly draw fluid on their own, ensuring a continuous flow and making the process more efficient.
Mechanical Diaphragm Design
These pumps quickly draw fluid on their own, ensuring a continuous flow and making the process more efficient.
Eccentric Block Actuation
Hunter Pumps use an eccentric block to actuate or move the diaphragm, making the pump action smooth and consistent.
Effective Suction Lifts
They can lift fluids from lower le
Wastewater Treatment Expert
Given their design, these pumps excel in wastewater treatment scenarios, ensuring the process is efficient and reliable.
Handles Abrasive Liquids
These pumps are built to manage rough liquids, which can be abrasive or gritty, without causing damage or wear to the pump parts.
Reliable Fluid Introduction
The pumps are adept at consistently introducing fluid, making them reliable for regular and heavy-duty applications.
Durability
Built with a sturdy design, Hunter Pumps ensure longevity and consistent performance over time.
HOW DOES A MECHANICAL DIAPHRAGM PUMP WORK?
Starting Position
At the onset, the chamber's one side is dominated by the diaphragm, a flexible disc. Ball valves securely block both the inlet and discharge ports.
Suction Stroke
When the mechanical shaft draws the diaphragm inward, the chamber's volume increases. This action reduces the internal pressure, causing the ball valve at the inlet to open. The external fluid is then drawn into the chamber, filling the space created by the retracted diaphragm.
Discharge Stroke
With the commencement of the discharge phase, the mechanical shaft pushes the diaphragm forward, decreasing the chamber's volume. This action increases the internal pressure. Consequently, the ball valve at the inlet closes, and the ball valve at the discharge port opens, allowing the fluid inside the chamber to be expelled.
MECHANICAL DIAPHRAGM PUMP INSTALLATION AND MAINTENANCE
Installation
Compatibility
Check
- Before setup, ensure the pump's specifications align with the fluids and temperatures you plan to work with.
Safety
First
- Always wear protective gear, such as safety goggles and gloves, during pump operation.
Proper
Training
- Always wear protective gear, such as safety goggles and gloves, during pump operation.
Pressure
Precautions
- Abide by the manufacturer's guidance and never exceed the pump's maximum operating pressure.
Piping System
Care
- Guarantee that the suction and discharge pipelines are independently supported to avoid undue stress on the pump's components.
Maintenance
Regular
Inspection
- Periodically examine the pump for signs of damage or wear.
Air End
Maintenance
- Should issues arise on the air side of the pump, pay close attention to both the main air valve assembly and the pilot valve assembly.
Thorough
Cleaning
- Before inspecting the pump internally, ensure it's fully drained of all chemicals or fluids.
Component
Care
- When replacements are necessary, always opt for genuine parts to maintain compatibility and to ensure longevity.
Re-torque
Fasteners
- Prior to pump operation, confirm all fasteners are adequately torqued. Over-torquing can result in pump damage.
Safety Note: When working with mechanical diaphragm pumps, especially when handling potentially harmful or corrosive solutions, always prioritise safety. Regular maintenance not only ensures smooth operation but can significantly extend the pump’s lifespan.
