Aquariums require pumps to filter water. Aquarium pumps drive water into or out of filtration systems. The most commonly used aquarium pumps are power filter pumps, aeration-powered pumps, external pumps and submersible pumps. Pumps operate by generating pressure differences between intake and outgoing valves. Aeration Pumps Aeration pumps take advantage of the force air places on water in a tube. As air is pumped into a water tube, the continuous stream of rising bubbles “drags” water along its upward motion. Aeration filters are very inexpensive and commonly used in small aquariums up to 20 gallons. A vibrating pump creates air pressure along a tube and is connected to either the base of the intake or the return part of the filter. If the pump is connected to the return tube, a siphon is used to bring the water into the filter. If the pump is connected to intake tube, gravity is used to return the water. Power Filter Pumps Power filters are magnetically driven. They are attached to the filter, usually sliding together and acting as a single unit.

Power pumps use two magnets; one is attached to an impeller inside the filter, and another is attached to the motor. As the magnet on the motor spins, it causes the magnet attached to the impeller to spin as well. The spinning impellor pushes water along a tube, either to or from the filter. fish tanks for sale inland empireExternal Pumps External pumps are maintained outside of the aquarium and have three classifications: centrifugal, diaphragm and peristaltic. buy cheap aquarium suppliesCentrifugal pumps, like the attached power filter pumps, are magnetically driven. boyu fish tank setup instructionsA spinning impellor forces water to the outsides of the impellor housing and through a tube. naat zain ul abideen jalali

The impellors and motors are larger and much stronger than those on power filter pumps. They can pump large volumes of water through filtration system in short periods of time and are usually used on larger tanks (55 gallons and up). fish tank fish not swimmingDiaphragm pumps deliver water in pulses as a motor opens and closes the diaphragm, forcing water to enter and exit a chamber. fish tank fish picsPeristaltic pumps employ rollers along flexible water tubes to pump water. As a roller glides over the tubing, the water is pushed in the direction of the roller. Peristaltic and diaphragm pumps are used by more experienced hobbyist who want to maintain very specific water quality parameters. Submersible Pumps Submersible pumps are magnetically driven pumps that are placed inside the aquarium. They are efficient, convenient and small, but come with a few caveats.

Submersible pumps generate heat and could end up overheating the aquarium. Since it is submerged, great care and attention must be given to the electrical lines to avoid shorts and electric shocks.

They come in all shapes and sizes, and may be operated by electric motor, engine, or even by hand or solar power. This guide will highlight the most common pumps, their uses, and how they are designed to work. Tip: Never use a pump to transfer flammable or corrosive materials. The higher your pump’s gallons per minute and horsepower rating, the more speedy and powerful it will move fluid.

Performance factors to consider when selecting a pump: Capacity and power: Capacity is how much fluid the pump can move and it’s measured in gallons per minute or gallons per hour. Power is measured in horsepower. Materials: Pumps are made of a variety of sturdy materials, including sheet metal, cast iron, stainless steel and other materials. Power sources: Include electricity, gasoline, diesel, hydraulics, natural gas, compressed air or manual. Head: Head pressure describes how powerful a pump is. Vertical discharge head pressure describes the vertical lift in height at which the pump can no longer exert enough pressure. There are four primary types: sump pumps, sewage pumps, well pumps and utility pumps. Each operate in a similar fashion, but serve different purposes. Sump pumps: Remove water that collects in basins from around a home’s foundation. See the chart for more detailed information. Motor is open and installed above water level. Open motor is exposed to dust and moisture

Should be positioned where motor cannot be submerged May operate 25 – 30 years Motor is sealed and unit is installed below water level May require a larger up-front investment Placed down in the sump pit Safer if children are in the house Functions even when submerged Sealed design prevents dust and moisture from affecting operation Ideal for finished basements May operate 5 – 15 years Use either pedestal or submersible; operates using battery power Runs on rechargeable batteries for up to 7 hours Look for units that alert you via a light or sound when problems occur Available in a range of capacities Discharge pipes may be separate or shared with primary pump Sewage pumps: Designed to pump liquids and semi-solids in a basement or below-grade area from a sewage basin up to the main sewer line for removal. The higher the lift or longer the distance the waste must be pumped, the more powerful the pump needs to be.

Well pumps: Provide water from underground to your home. See the chart information about different types of well pumps. Shallow Well Jet Pump Pump sits above ground and draws water out through one inlet pipe For depths to water 25’ deep or less Sits above the ground One-way check valve keeps pump primed Deep Well Jet Pump Pump sits above ground and draws water out of one pipe and pushes water through another pipe For depths to water 25 to 110’ deep May include a tailpipe to ensure well is never pumped out Requires a foot valve to prime the pump Deep Well Submersible Pump A single pipe comes up from the inside of the well into the home and connects to a pressure tank Operate in depths to water 25’ to 400’ deep Must be pulled from well casing for repairs 2-wire pumps have built-in controls 3-wire pumps require a separate control box Utility pumps: Used for short-term purposes or emergencies to move liquids from one place to another.

The chart provides information about different types of utility pumps. Motor is housed in a water tight compartment so the pump can be fully immersed in liquid Power ranges from 1/6 – 1/4 horsepower Can have manual or semi-automatic activation Dewaters down to the bottom intake at 1/6” or 1/8” off the surface Manual pumps turn on when plugged in Semi-automatic units turn on when plugged in and detect water periodically for motor draw A specific model of the submersible pump that removes water from your pool cover Activation may be manual or semi- automatic, depending on the model Usually come with a long cord Some models have leaf screens Transfer models move water from location to location via hoses In addition to transferring water, boosting units increase pressure where low or inadequate water pressure is an issue Available in a variety of sizes and power, from light aquarium applications to heavy dewatering

Boosting units add pressure for car washing or sprinkling Remove collected condensation from gas or electric furnaces or air conditioning units Available as manual or automatic units for convenient operation Lawn sprinkler pumps: Used to draw water from various sources to lawn sprinkler systems. Pond and waterfall pumps: Powers water flow and circulation for decorative water features.Inflate bike tires, sports balls and portable mattresses. Swimming pool pump: Circulates water through a swimming pool, filters debris, and cleans water to keep it clear of contaminants. Hot water recirculating pump: Provides hot water at every faucet or shower when you need it. Pump Designs and Features How a pump is designed determines the way in which it moves fluids. And there are several convenient features to consider, from the ability to adjust the pump speed, to backup power that will ensure operation in case of a power outage. Centrifugal pumps: Accelerate liquids with a revolving device called an impeller, which pushes liquids out through a valve opening.
