After using several of the “Big Name” pumps I was sure there wasn’t a product on the market that could move our drilling mud. I was having to use an excavator and two dump trucks to move the mud. We found Gator Pumps and purchased a 12″ PTO driven pump. We were able to move our mud in half the time with less effort. What used to require three pieces of machinery and three operators now requires one tractor and one worker checking on the pump periodically. We also use our Gator Pump to pump rain water off our pits. The pumps are almost maintenance free and absolute workhorses. Save yourself the frustration of trying to find the right pump for your operation. Just call Dale and the guys at Gator. They’ll fix you up and you won’t be disappointed.

GATOR Pumps have been used by agricultural producers worldwide for over 40 years.  Our pumps were originally designed to give the farmer a portable, reliable pump that he could quickly employ for all pumping operations.

Our pumps operate in canals, ditches, ponds, streams and lakes without suction lines or priming.  We can filter out materials that clog sprinklers and nozzles that feed pivot systems.  GATOR Pumps can be trailer mounted or in 3-point tractor hook-up for easy and portable one-person operation.

At GATOR Pump, Inc., our pumps have been used by agricultural producers worldwide for over 40 years. They were originally designed to give farmers a portable, reliable solution for all of their pumping operations. While they’ve since found use in many other demanding industries and applications, they continue to serve as a key piece of equipment in the agricultural industry. Whether your application involves pumping water from flooded fields, supplying water to flood and furrow-irrigated farmland, or driving pivot sprinkler systems, there is a GATOR pump to fulfill your needs.

In the agricultural industry, industry professionals make extensive use of pumps for irrigation and other water management purposes. The equipment enables them to move massive quantities of water quickly. Compared to older water management methods, it accommodates much higher volumes (typically hundreds or thousands of gallons per minute), which is necessary to keep various growing and harvesting operations running smoothly and efficiently.

There are many types of water pumps for agricultural applications. Each one varies slightly with regard to design and configuration, making them suitable for different operations. Some of the key factors to keep in mind when choosing one for a particular operation include a water source, desired flow rate, desired total suction head, and desired total dynamic head. Irrigation pumps for small fields located immediately beside a water supply do not have the same requirements as those used to flood large fields from a distance. Portability and compatibility with existing equipment are also essential. The former is important for operations that require the distribution of water from several different water sources to several different sites, while the latter is important if the operation already has an existing irrigation setup.

One of the most commonly used types of irrigation pumps is the power take-off (PTO) pump. It is designed to connect to tractors and use the power from the driveshaft to move water. They serve as an easy and convenient pumping solution for agricultural professionals with existing tractor equipment or power sources.

General water management, such as water transfer (from ponds, canals, ditches, and rivers to agricultural sites for crops and livestock as well as towns and villages for homes and businesses), sludge/sediment removal, water intake dredging, and tail-water reuse

GATOR Pump serves the agricultural industry by providing durable, reliable, and easy-to-use pumps. Our products can be used in canals, ditches, ponds, streams, and lakes without suction lines or priming. Additionally, they can filter out any materials that clog the sprinkler and nozzle components of pivot systems to reduce the risk of blockages occurring and can be configured for trailer-mounting or three-point tractor hook-up to facilitate multi-person or one-person operation.

Our standard pump offering is the GATOR power take-off (PTO) water pump. It was designed specifically for use in the agricultural industry, providing excellent power and performance while requiring minimal setup and maintenance. Its portability and compatibility enable agricultural workers to transfer water in any application that accommodates a trailer, from flooding water to farm fields to removing water from flooded fields.

Considering there are no suction lines, no priming or check valves, no mechanical seals, and no internal parts other than an impeller, the GATOR Pump is by far the most durable, maintenance-free, cost-efficient option for the farmer or agricultural producer. In addition, our in-house artisanal manufacturing means that customization is easy at the time of purchase. For example, we’ve had previous customers add a diesel engine or electric motor, relocate/swivel the discharge pipe onto one of our pumps to aid in mobility.

A part of National Oilwell Varco, the Mission line of centrifugal pumps are equipped with innovative features to match the demanding nature of routine, corrosive and abrasive applications. Because of the need for a low pressure mud system, Mission 1780 Type W centrifugal pumps were introduced in 1950s to replace duplex pumps. The aim was to apply a high quality centrifugal pump with concentric systems that allowed for abrasive fluids to be mixed and transferred thereby lowering the initial and maintenance costs of drilling. As a result, centrifugal pumps with low pressure mud systems such as Mission 1780 Type W became the industry standard.

As well depths increased, so was the need for heavier mud weights and centrifugal pumps that could withstand greater horsepower load. This led to the launch of Mission Magnum- a centrifugal pump.

The Magnum has an open impeller design that contains wide-tipped vanes and a more tangential circumference of the suction allowing the pump to create a smoother flow pattern when handling abrasive fluids. The Magnum is available in Magnachrome™, hard iron, stainless steel, and aluminum bronze fluid ends. The pumps can be unitized with electric motors, diesel engines, and hydraulic motors (horizontal, vertical, or close-coupled configuration).

Our pump engineering experts have the industry knowledge to gladly assist you with any questions, concerns, or inquiries you may have regarding the pumps & pump parts we distribute @ 800.560.7867.

The condenser water pumps take hot water from the condenser to the cooling tower, and the chilled water pumps take cold water from the chiller to your AC unit.

When the pump fails, water is not circulated as efficiently or at all, compromising the performance of your entire system. Thankfully, pumps often signal that there is something wrong, and these signals usually come in the form of odd and loud pump noises.

Loud and unusual sounds emanating from circulating pumps are always a red flag, a sign that something is wrong either with the pump or in the water lines.

If you don’t have an air separator installed, you will most likely have to deal with air in your system at some point. When this happens, it’s important to inspect the water lines and bleed the system.

Modern pumps have bleeder valves that make the process very easy. Slowly open the valve until you start hearing a hissing noise. Once the hissing ceases, you will see a slight dribble of water, indicating that the pump no longer has air. At this point, you can close the valve.

After doing this, make sure that the pump has been installed correctly. Even a few degrees of inclination or misalignment will allow air to get locked in the pump.

Pumps can be oversized for several reasons. It could happen due to a degree of error in the planning and design stage when engineers need to “guesstimate” piping length and fittings, or it could be purposely designed this way so the system can expand in the future and the “right-size” pump today would not be able to meet the future demand of tomorrow.

Sometimes a pump replacement is needed right away, and the supplier didn’t have the perfect replacement in stock, or the engineers choose an oversized pump already considering an expected build-up of corrosion in the pipes that require more pump head.

Regardless of the reason that led to an oversized pump, having one can always cause excessive noise and vibration, loosing up connections and joints and causing piping fatigue.

Under sizing a pump presents a more serious issue. That’s because you, unfortunately, don’t have much choice other than replacing the pump and installing a larger one.

If the system is undersized, it can’t provide the duty needed, it can also lead to deadheading - when a pump’s discharge is closed because of a blockage in the line or an unintentional closed valve. When this happens, the fluid churns inside the pump until it heats up into a vapor, causing noise and damage. Deadheaded pumps can lead to motor burn out, a damaged impeller, seal leakage, cracked bushings, and compromised elastomers, ultimately killing the pump.

In systems with undersized pumps, you can verify if the existing pump can handle a larger motor to avoid dead head. Even though it may be the cheapest way to handle the problem, it is not the best and the solution would just be temporary.

Only some pumps have bearing assemblies, not all. However, all electric pump motors have bearings, and the excessive wear of bearings – whether on the assembly or inside the motor - can cause pump noise.

The good news is that pump models with bearing assemblies usually have the components available for purchase, and they are inexpensive and easy to replace.

The life of a bearing is determined by how many hours it takes for the metal to “fatigue,” but many factors can affect this, such as static overload, corrosion, lack of excess of lubricant, overheat, misalignment, and contamination. So, the best way to avoid bearings from wearing out too fast is via preventive maintenance and a comprehensive inspection of your system.

Water with rust and other sediments can wear out the circulating pump and clog the impeller. When this happens, noise is a consequence. To get rid of it, there is no magic bullet: the solution is in cleaning the system.

Many HVAC systems have dedicated filtration systems and dirt separators to prevent clogging from happening. Sediments can be easily removed from the system through water blowdown.

High-quality and modern pumps usually have 3 flow settings, while older pumps may have only one or two. That’s why older pumps are typically noisier than others. They are less efficient, and the energy loss is usually translated into a humming noise.

If your pump is making this noise and you have more than one option of flow setting to work with, locate the flow switch and turn it down one level. Then check the radiators and tower rails to verify if they are still getting up to the temperature they should. If so, then leave it this way.

If you operate with a VFD and your pump is still making a humming noise, check to see if you have a correct grounding of the motor to the VFD. In many cases, incorrect grounding allows the system to act as a noise transmitter.

To understand this, we need to take a step back and take a quick look at pump operation. Bernoulli"s principle shows us that fluid flows from areas of high pressure to areas of low pressure.

HVAC pumps operate by creating low pressure at the inlet, allowing the water to be pushed into the pump. As the fluid flows through the pump, the pressure decreases. If the pressure at the inlet happens to fall below the vapor pressure of the fluid, air bubbles form at the inlet. These bubbles can cause cavitation, leading to pump noise, damage, and lower capacity.

Net Positive Suction Head or NPSH is the difference between liquid pressure at the pump suction and liquid vapor pressure and is expressed in terms of the height of the liquid column. NPSH needs to be usually 3 to 5 feet to avoid cavitation.

If detected in an inspection that there’s a problem with the NPSH, basically two things can be done: first, there’s the option to choose a more appropriate pump for the application (our recommendation if the pump has already suffered irreparable damage due to cavitation). Second, the system can be reevaluated to see if elevating the cooling tower can increase NPSHa (the absolute pressure at the suction port of the pump) or if fittings that rob current NPSHa can be reduced.

If you need assistance with anything related to circulating pumps, contact us. We have 3 offices in California, and we can go wherever you are to inspect your pump if you are experiencing loud and unusual noises.

The Vertical Systems team of sales engineers and technicians can point out the cause of pump noises, and determine the best solution to eliminate it.
