Syringe pumps

Are used for processing materials that require exact flow amount at exact time intervals. There are two types of syringe pumps: withdrawal pumps remove the fluid and infusion pumps process fluid at highly controlled pressures.

Sanitary pumps

Are used in applications that require a higher level of sanitation such as in food, breweries, and biotech companies. This type of pump can also move slurries and meter solutions. Sanitary pumps offer a variety of pump types and features.

Progressive cavity pumps 

Aare used for moving slurries and fluids with suspended solids. The fluids are moved from one side of the pump (suction) to another side (discharge) and then to a storage tank or through a pipeline. Cavity pumps can efficiently transfer slower-moving viscous materials and fluids from these pumps can be moved in a continuous flow. They can be used in applications requiring greater sterility and sanitation since they can be easily cleaned.

Positive displacement pumps

Use pistons, gears, diaphragms, and other devices to pump fluids through. They are also moved by a vacuum created when the fluid is pumped into a fixed cavity and then pumped out again, creating a vacuum that sucks in other fluids. Displacement pumps are best used on viscous liquids that are under great pressure. They have many applications and offer a variety of features.

Corrosion resistant pump
This pump utilizes recessed impellers to handle extra solids while minimizing abrasive wear. The pump has specialty coatings for corrosion resistance, which minimizes abrasive wear and increases the pump's lifetime. Our submersible pumps are fortified by stainless steel (not fabricated sheet metal, like less expensive pumps).

Agitator slurry pump
This pump utilizes kinetic energy to agitate the slurry into a state that's fluid enough for transportation. Without this energy, the pump would only transport water, leaving slurry to accumulate around the intake, eventually starving the pump. The mechanical agitator enables it to transfer stubborn elements such as settled mud, silt, slurry, and sand. Use this in industrial settings to pump heavier concentrations and larger quantities of sediment.

Solids handling pump
This pump can transfer moderate to heavy suspended solids such as sewage, debris, and slurry. This pump is popular for use in lagoon applications (animal & vegetable waste, wastewater) and trash applications (where solid buildup is too substantial for de-watering pumps). It can pass up to 3" size solids, making it a popular sewage pump.

Dewatering pump
This pump can transport water or water with light suspended solids. Corrosion-resistant coatings and float switch/control accessories are available for add-on. Especially useful for waterfront properties, flooded mines, and construction sites, these pumps provide strength, longevity, and efficiency.

Locate the pump as close as possible to the liquid to keep suction lift to a minimum. The shorter the distance a pump has to move liquid, the more volume it will deliver. Longer hoses produce more friction and less volume.

A significant difference exists between using a trash pump and a high-pressure pump when supplying water to large sprinklers. Trash pumps are designed for high flow and low pressure. High-pressure pumps are designed to deliver water at higher pressures.

For example, a 2-inch trash pump pumps 50 gpm at 35 psi. At the same time, the 2-inch high-pressure pump pumps 50 gpm at 65 psi. For your large sprinklers to perform at their best, flow needs to be delivered to the sprinklers at high pressure.

It would help if you considered friction loss while choosing a trash pump. Small hose sizes will lead to more significant friction loss. Accordingly, you must consider the fluid volume being moved to size the appropriate trash pump. Generally, 3-inch pumps ensure a flow rate of 200 gallons per minute (GPM), while 18-inch pumps can move between 10,000 to 11,000 GPM. Both hose size and volume go hand in hand to achieve the necessary flow rate.

Pump capacity and power
There are different types of trash pumps, including submersible, diaphragm, and centrifugal pumps. Each comes with its unique features, suitable for specific conditions. They also have different pump capacity and power. For example, centrifugal trash pumps can lift fluids to 25 feet, while trailer-mounted trash pumps may lift them as high as 150 feet.

Moreover, other factors play into consideration, such as the volume of water, the nature of debris, and head height. You need a high-capacity pump for larger volumes, abrasive debris, and higher head heights.

Accordingly, trash pumps have different power options. You can choose from electric, gasoline, and diesel trash pumps according to your needs and preferences. Electric pumps are recommended for areas with access to electricity, while the others are preferred for portability and fuel efficiency.

Portability and mobility
Some projects may require mobility as you would need to move it between different job sites to ensure the project's completion. Hence, the size and weight of the trash pumps become a crucial factor. Smaller and more portable trash pumps are available but often have lower capacities. However, they are easy to maneuver and transport.

Some pumps have additional features, such as wheels or handles, to make transportation easier. Larger heavy-duty trash pumps often come with the option to be pulled behind a trailer. Their design also plays a crucial role in its maneuverability.

Durability and build quality
Trash pumps are designed using different materials for different purposes. Common ones include cast iron, stainless steel, aluminum, and plastics or composites. Cast iron trash pumps have increased durability and wear resistance, which is common in heavy-duty units.

Stainless steel plays an essential role in handling corrosive substances. Accordingly, aluminum offers the right balance of strength and portability. Plastic and composite trash pumps are often used in less demanding applications. They are lightweight and may provide resistance to certain chemicals.

Ease of maintenance
Regular maintenance ensures trash pumps operate at peak efficiency, experience fewer breakdowns, and enhance longevity. Accordingly, neglecting its maintenance can lead to increased wear and tear, reduced efficiency, and frequent breakdowns.

Therefore, trash pumps with user-friendly maintenance features should be considered. Most trash pumps have additional features to provide easy access to essential cleaning, inspection, and repair components. It can reduce the time and effort for routine maintenance.

You should also check for availability of replacement parts to ensure less downtime. Accordingly, you must ensure its maintenance activities are laid out in its documentation and user manuals. Some manufacturers provide technical support, tutorials, and online resources to help with the trash pump's maintenance.

Safety features
Trash pumps have different safety features to protect the equipment and the operator. They are necessary to ensure the pump's longevity and prevent accidents. Standard safety features include overload protection, automatic shut-off, and safety switches.

Overload protection helps prevent the motor from burning out when the pump operates beyond its capacity. It allows the pump to avoid overheating or mechanical failures. Automatic shut-offs deactivate the pump when it detects an anomaly, such as the pump running dry, a drop in oil pressure, or overheating.

Accordingly, safety switches function as emergency stop buttons, allowing operators to turn them off during emergencies. They are necessary to prevent equipment damage or accidents. Other safety features include thermal protection, leakage sensors, and ensuring a stable and durable site for installation.
