Managing fluid transfer across diverse global sectors, from mining and chemical processing to hygiene & pharmaceuticals, requires a focused approach to engineering. Ovell, as a leading diaphragm pump manufacturer, offers a comprehensive portfolio of solutions designed to meet the varying demands of these critical industrial processes. This portfolio includes robust standard pumps built for high-volume utility applications and highly specialized pumps engineered to handle complexities like dry powders, abrasive slurries, and precise chemical dosing.

Standard Pumps: Versatility in General Fluid Transfer

Ovell’s standard pump line serves as the industrial workhorse, providing reliable, cost-effective solutions for the most common fluid handling applications. These units are built around the durable air operated double diaphragm pump design, offering portability, submerged operation capability, and efficient utility transfer across various industries. The key difference among these standard models lies in their primary material of construction, which determines their suitability regarding chemical compatibility, temperature tolerance, and general operating environment.

Plastic Air Diaphragm Pump

This pneumatic diaphragm pump is constructed using materials like polypropylene or PVDF. This material selection makes the pump inherently resistant to a broad range of corrosive acids, alkalis, and aggressive chemical agents.

• Industry - Chemical Processing: A core challenge is transferring highly corrosive and potentially hazardous chemicals without causing degradation to the pump casing, ensuring operator safety and environmental protection.
• Product Case Use: Handling aggressive etching chemicals or strong cleaning agents in a plating or semiconductor facility. The plastic construction prevents external corrosion and maintains containment integrity.

Stainless Steel Air Diaphragm Pump

This durable metal double diaphragm pump is constructed from high-grade stainless steel. It is chosen for its strength, resistance to high temperatures, and non-reactive surface finish, which is important for maintaining purity.

• Industry - Food and Beverage & High Temperature Applications: Challenges include pumping moderately viscous fluids at elevated temperatures and requiring metallic durability and resistance to wear and tear.
• Product Case Use: Transferring hot oils, solvents, or concentrated syrups in a blending facility, where the stainless steel construction ensures durability against pressure and heat without contamination.

Aluminium Air Diaphragm Pump

The aluminium design is robust and cost-effective, making it the ideal choice for general, non-corrosive industrial applications. This type of pump is typically the default for neutral fluids and solvents.

• Industry - General Industry & Manufacturing: The challenge is finding an economical yet robust pump solution for continuous circulation, utility transfer, or waste removal of low-risk, non-abrasive fluids.
• Product Case Use: Circulating coolants, transferring industrial lubricants, or managing wastewater streams that are largely neutral and free of heavy abrasive solids within an automotive or machinery manufacturing plant.

Specialty Pumps: Engineered Solutions for Complex Challenges

The specialty range of pumps is purpose-built to address the demanding fluid characteristics and compliance requirements that standard pumps cannot safely or efficiently handle. This category includes highly modified air operated double diaphragm pump designs, as well as specialized electric and metering units. These products are critical for handling high viscosity, dry solids, abrasive slurries, high pressure, and applications that require absolute dosing precision or hygienic compliance.

Precision and Compliance in Complex Fluid Transfer

Pneumatic Powder Pump

This pump is a specialized pneumatic powder diaphragm pump designed to fluidize and transfer dry, fine materials. Its design uses low-velocity, high-volume cycling to minimize friction and prevent compacting, making it ideal for cohesive, dry solids transfer.

• Industry - Ceramics and Pigments Manufacturing: The transfer of dry, fine materials poses a severe challenge due to the inherent friction and tendency of powders to cake or bridge, requiring specialized handling methods to prevent expensive downtime and contamination.
• Product Case Use: Utilized for transferring dry ceramic glaze powders from bulk bags to mixing hoppers, ensuring accurate batch weighing and formulation while containing the material, crucial for safety and product consistency.

FDA Diaphragm Pump

This pump is constructed exclusively from food-grade materials, such as 316 stainless steel with a passivated satin finish and fda-certified ptfe diaphragms. Its design is built to eliminate leak points and dead zones, ensuring compatibility with clean-in-place (cip) processes.

• Industry - Food and Beverage Production: This industry faces the constant, non-negotiable challenge of maintaining hygienic integrity and avoiding product contamination, often dictated by stringent regulatory bodies.
• Product Case Use: Transferring high-viscosity, shear-sensitive foodstuffs, such as tomato paste or concentrated fruit juices. The pump’s gentle action preserves product quality while meeting rigorous sanitary regulations.

Booster Diaphragm Pump

This pump is engineered to multiply the air inlet pressure into a significantly higher fluid discharge pressure. It is used to take an existing fluid supply and increase the discharge pressure to overcome system resistance.

• Industry - Chemical Processing and Manufacturing: A key challenge involves supplying viscous liquids or adhesives at sustained high pressure to remote or multiple dispensing points where system resistance is high.
• Product Case Use: Utilised to supply high-pressure glue or sealant to multiple robotic dispensing heads on a high-speed automotive production line, ensuring a uniform bead application and adhesion across complex components.

Handling Viscosity and Solids: Electrically Driven Solutions

Flap Valve Diaphragm Pump

This pump is a specialized industrial diaphragm pump that replaces traditional ball check valves with weighted, hinged flaps. This modification creates a wide, unobstructed flow path through the pump.

• Industry - Water and Wastewater Treatment: Slurry management presents a significant challenge: transferring thick, abrasive mediums containing large, suspended solids without constant clogging or internal pump damage.
• Product Case Use: Pumping thick, abrasive dewatered sewage sludge or transferring concrete slurry mix from a pit on a construction site. The wide opening allows large solids to pass through smoothly without causing blockages.

Electric Diaphragm Pump

The electric diaphragm pump (eodd) is mechanically driven by an electric motor, allowing for superior energy efficiency and precise flow control through variable speed drives.

• Industry - Oil & Gas (Remote Installations): This sector often faces challenges with energy inefficiency and high noise levels associated with extensive compressed air infrastructure in remote or enclosed spaces.
• Product Case Use: Transferring lubricants, coolants, or low-viscosity fuels at a remote oilfield location where reliable electric power is available and maintenance of air infrastructure is limited, offering significant cost savings.

The Critical Role of Precision in Fluid Dosing

Diaphragm Metering Pump

The diaphragm metering pump is a highly accurate, positive displacement pump designed for the precise dosing of chemicals, acids, and catalysts into a main process stream.

• Industry - Hygiene and Pharmaceuticals: Process integrity hinges on accurate chemical dosing. The challenge is introducing potent chemicals into a stream at a minute, precise, and highly repetitive flow rate.
• Product Case Use: Injecting concentrated biocides or flocculants into a municipal water treatment line, or accurately dosing active pharmaceutical ingredients (apis) into a batch reactor during drug manufacturing, with a leak-free design that enhances safety.

Diaphragm Pulse Dampener

This is a critical accessory installed on the discharge side of a diaphragm pump to absorb the natural pressure fluctuations (pulsations) created by the pump’s reciprocating action.

• Industry - Paints and Coatings: The challenge is achieving a uniform spray finish, as the reciprocating action of an air powered diaphragm pump creates pressure pulsations that can lead to uneven coating quality.
• Product Case Use: Ensuring a uniform flow of high-solids paint or resin through a long distribution line to a spray booth or coating machine, preventing pressure spikes that would otherwise cause uneven application and damage sensitive equipment.
