What is the maximum flow rate of the PA200S pump?

The PA200S has a maximum flow rate of 69 GPM at 190 RPM with water (SG 1.0) at ambient conditions.

What is the maximum flow rate of the PA300S pump?

The PA300S has a maximum flow rate of 158 GPM at 280 RPM with water (SG 1.0) at ambient conditions.

What repair kit is compatible with the PA300S pump?

The PK300S 3-inch stainless steel repair kit is fully compatible with the PA300S pump and includes all necessary components for complete rebuild.

Are NAPCO rotary gear pumps self-priming?

Yes. All NAPCO rotary gear pumps are self-priming and bi-directional, meaning they can pump in either direction by reversing the drive rotation.

Does NAPCO offer repair kits for its pumps?

Yes. NAPCO offers factory-matched repair kits for every pump model. Each kit includes drive and idler gear assemblies, roller bearings, high and low pressure seals, and gaskets.

What is the difference between ductile iron and stainless steel NAPCO pumps?

Ductile iron pumps are built for rugged durability in mining and industrial applications. Stainless steel pumps provide corrosion resistance for chemical, food-grade, and emulsion applications.

How do I calculate the required pump flow rate for my application?

Divide the total volume to be transferred by the available time in minutes, then add a 15-20% safety margin for variations in operating conditions and pressure losses.

What gear material options are available?

Standard gears are high-temperature nitrile rubber rated to 240 degrees Fahrenheit. For higher temperatures or corrosive fluids, NAPCO offers EPDM, urethane, and Viton options.

Why is stainless steel required for emulsion explosives pumps?

Ammonium nitrate is inherently corrosive to carbon steel and cast iron. NAPCO stainless steel pumps ensure the entire wetted path resists corrosion.

What is the maximum operating pressure for NAPCO pumps?

NAPCO rotary gear pumps are tested up to 100 PSI discharge pressure.
