Types of NOV Well Service Pumps
The NOV Well Service Pumps produced by our company mainly include the following types:
NOV JWS-400 Caged Valves Pump
The hydraulic end of JWS-400 features a modular design, with each module being fully forged from high-strength alloy steel (35CrMo or 40CrMnMo). Compared to traditional cast or monoblock hydraulic ends, this modular forging structure offers unparalleled advantages.
NOV JWS-340 Special Pump
Our JWS-340 SPECIAL pump uses an all-in-one high strength forged steel power end housing. Compared with the common welded steel frame or cast iron frame in the industry, the forged steel frame has incomparable advantages.
NOV JWS-340 P-4 Valve Pump
The JWS-340 is designed to reduce your Total Cost of Ownership (TCO). Through continuous investments in material science, manufacturing precision, and component durability, it minimizes operational costs, reduces unplanned downtime, and enhances on-site safety.
Advantages of NOV Well Service Pumps
Tackles Tough Fluids with Ease
NOV pumps are designed to handle abrasive, viscous, and even solid-laden media like mine slurry, sludge, heavy crude, and food pastes.
Durable and Built for Harsh Environments
With a long track record in the mining and energy sectors, NOV well service pumps are made from corrosion-resistant materials, wear-resistant rotors, and durable elastomer stators.
Precision Metering and Dosing
NOV’s design offers consistent, pulse-free flow, making their PC pumps ideal for chemical dosing, polymer injection, and industrial processing applications where accuracy is critical.
Energy Efficient and Low Maintenance
NOV well service pumps reduce energy consumption with high volumetric efficiency and fewer moving parts. Their design also simplifies maintenance, with easily replaceable rotors, stators, and seals.
Mining – Tailings transfer, thickener underflow, dewatering
Oil & Gas – Drilling mud, waste oil, crude handling
Wastewater – Sludge transfer, biosolids pumping
Agriculture – Manure, effluent, irrigation additives
Food & Beverage – Sauces, syrups, dairy, and pastes
Installation Steps for the NOV Well Service Pumps
Disconnect All Power
Easily the first step, all power should be turned off at the electrical panel and the pump's control box if applicable, and tested with a voltmeter to ensure no electricity is flowing to the installation location.
Ground the System
Note that all wiring must meet National Electric Code and local electric code requirements for safety, so make sure to consult your owner's manual for information that may be unique to your deep well pump.
Test the Pump Before Installing
To test the pump before installing, you'll need to connect it to the proper power supply. The frequency and voltage must match the motor nameplate frequency and voltage. Next, you'll need to properly attach the supply wire leads and attach the copper ground wire to the motor bracket.
Mount the Control Box
Now that everything has been tested, it's time to install the control box. Again, see the owner's manual for specific instructions for your pump. Mount the control box in a permanent weather-proof location. Controls should never be exposed to moisture or excessive heat.
Install the Pump
If you are using a standard air over water pressure tank, you need to drill two bleeder orifices about two feet apart so they will automatically charge the tank with air. If a pre-charged tank is being used or is replacing a traditional tank system, do not create new orifices, and remove old ones if necessary.
Clear Out the Well
After the control box is set up and the motor leads have been connected, you'll need to attach a pipe elbow and a gate valve at the top of the piping temporarily in order to clean out the well. Set the gate valve on the discharge to be open one-third of the way.
Attach to Water Tank
Now it is time to attach the pump system to the water tank. Submersible tanks can cause high-pressure backups and even blow up, so be sure to install a pressure release valve that can pass full pump flow (follow local codes on this).
