What is a gear pump? Well, they are a kind of positive displacement pumps which displace fluids, including oils, fuels, and chemicals. They feature two intermeshing gears, which trap the fluid and transport it from the inlet side of the pump to the outlet side with every rotation.
Gear pumps are used in various industries, including oil, fuel, food, and chemicals. Among the gear pumps available in the market today, cast iron gear pumps are especially known for their strength and durability. Read on to learn about ten key features of high-quality gear pumps, especially the cast iron ones.
- Robust construction: High-quality gear pumps are made to handle fluids of all kinds, including abrasive and corrosive ones. These pumps have high thermal stability, which means they can survive high temperatures, making them suitable for applications that handle fluids at high temperatures.
- Built for efficiency: Any quality gear pump must be efficient, i.e. it should use energy to displace fluids with minimal loss. This quality is very important in industries where exact fluid measurements and flow rates are a requirement.
- Self-priming: Good quality gear pumps usually come with the self-priming feature, which enables them to create a vacuum at the inlet and draw fluid into the pump even when initially dry. Cast iron gear pumps are even better as they support quick priming without compromising performance.
- Versatility: High-quality gear pumps are suitable for applications in a wide range of industries. They can move oils, chemicals, lubricants, and food-grade fluids, among other things. Cast iron gear pumps are well-known for handling fluids with moderate to high viscosity, which is crucial in chemical processing and manufacturing sectors.
- They are compact: Gear pumps now come in compact designs that can be installed in confined spaces.
- High-pressure handling capability: Good quality gear pumps can handle higher pressure better than other pump types. This makes them ideal for applications involving hydraulic fluid transfer. This feature allows them to perform well in heavy-duty industrial tasks where maintaining high pressure is critical for efficiency and quality.
- Low maintenance: Since gear pumps have fewer moving parts and are made of solid, wear-resistant materials, they require very little maintenance. These pumps also have easily accessible parts that can be quickly inspected and replaced when needed.
- High suction power: A high-quality gear pump offers superior suction capabilities that come in handy in applications that work with high-viscosity fluids or materials with low flow rates. High-quality gear pumps maintain excellent suction even at low speeds, minimising cavitation risk and allowing for smoother, more efficient operation.
- Silent operation: While several gear pumps tend to be loud because of all the meshing of gears and high-speed operation, the high-quality ones are usually designed to absorb sound and minimise the clanking of parts.
- They can work with all kinds of temperatures: Many gear pumps, especially cast-iron ones, are built to handle hot and cold liquids. This feature makes cast iron gear pumps particularly valuable in industries such as oil and gas, where fluids can often reach high temperatures.
Viking Pumps – Serving excellence since 1911
Viking Pumps is a well-known name in the pumping industry, with over 245 authorised distributors in 68 countries. Viking pumps offer resilient, robust, high-performing pumps that can handle over 1,400 types of fluids. These gear pumps simply perform. With construction options designed to work for light, medium, and heavy-duty applications, these pumps offer a simple design, high efficiency and consistent flow rates.
Universal Seal Series – The pumps in this series are made to work with applications that require continuous duty at pressures up to 200 PSI. They can operate under suction lift conditions and handle even higher pressures if there are high-viscosity fluids.
Universal Mag Drive Pumps – The Viking Mag Drive series promises a leak-free magnet drive design that is perfect for handling hazardous, hard-to-handle fluids.
Spur Gear – The SG series is engineered to offer reliability even amidst high-pressure environments. This series can handle pressures up to 2,500 PSI.
DFO Skid – DFO stands for Duplex Fuel Oil Skid. The pumps in this series are designed to offer auxiliary supply support skid to applications such as generators, boilers, etc., for emergency fuel supply.
To sum it up, gear pumps, especially the ones made of cast iron, offer several advantages. From high accuracy to versatility, reliability and easy maintenance, these pumps are trusted by operators in several industries where precise metering is required to ensure product quality and safety. However, while selecting the right gear pumps, it is important to go for a well-known brand that delivers efficiency and performance, such as Vikings.
