All You Need to Know About ProPortâ„¢ Casings
Internal gear pumps from Viking Pump's latest generation, available in steel and stainless steel sizes ranging from H to QS, bring a host of advantages over their predecessors made of alloys, especially when it comes to porting flexibility. These new pumps have streamlined the production process by reducing the number of casing configurations, cutting down on manufacturing complexity, costs, and lead times, while simultaneously expanding porting options and offering greater flexibility in port placement.
Our users emphasized the need for adjustable port sizes based on viscosity. For low viscosity fluids, smaller ports help reduce piping expenses, whereas larger ports for high viscosity liquids minimize friction losses and energy consumption. As such, each pump size now offers multiple port size options and conforms to various global standards and pressure/temperature specifications.
Previously, Viking Pump manufactured numerous casings due to ports being integrally cast into the casings, necessitating unique casings for each port size and standard option. This resulted in a vast array of casings to meet every requirement worldwide.
A major innovation in the new ProPortâ„¢ casings is the switch to bolt-on rather than cast-in ports. This change has dramatically decreased the number of unique casings from 372 to just 14. To put this into perspective, distributors can now stock a range of sizes with the ability to quickly swap out ports to cater to customers' specific piping needs.
For instance, the K and KK size pumps now offer bolt-on 2†NPT ports, ANSI-compatible Class 150 raised-face flanges in 2â€, 2-1/2â€, 3â€, and 4†sizes, Class 300 in 2â€, 2-1/2â€, and 3†sizes, as well as DIN 50, 65, and 80 PN16 ports. Consequently, a single casing used for both K and KK sizes includes 11 bolt-on port options, with internal porting sized to fit the largest available port. Refer to the table below for available port options.

Fig. 1 - Port Options for ProPortâ„¢ Casings
Beyond the benefits of flexibility, lead time, and pricing, the Modular pumps’ ProPort™ Casings bring additional advantages:
- Removable NPT threaded ports on H-L size pumps eliminate the need for unions in the suction and discharge lines that were previously necessary to remove an NPT-ported pump.
- All ports can be reused, so if a replacement pump is needed, it can be ordered with fewer ports to further reduce costs.
- Bolt-on ports can be sealed by gaskets or O-rings and were designed and tested to ensure nozzle load ratings exceed ASME, DIN, and other global standards.
- Distributors can provide enlarged suction ports to minimize friction losses that reduce NPSHa and prevent cavitation, while using smaller discharge ports to keep piping costs low.
Interestingly, Viking pumps are traditionally known for having 90° ports, typically for side suction and top discharge piping to pump to overhead lines. However, some customers expressed a desire for more opposite port options. While some opposite port models were available, they often came with longer lead times and higher prices. Surprisingly, in reducing the number of casings from 372 to 14, Viking Pump actually introduced opposite port models in all sizes, H through QS (with capacities from 30 to 500 GPM or 3.5 to 114 m³/hr). This represents 26 times fewer casings, yet offers more customer-focused options! Moreover, these new casings are fully retrofittable onto existing Viking pumps.
Another improvement is that the new ProPortâ„¢ casings are gasketed but also come with O-ring grooves as standard to allow static O-ring seals if needed. Previously, Viking Pump's alloy pumps used gaskets to seal the bracket and head to the casing because gaskets were compatible with nearly every liquid and simplified product selection. However, some customers preferred O-ring seals, which required machining special grooves at higher cost and longer lead times.
Additionally, casing drains were once optional and added cost and lead time, but they are now standard, allowing for nearly complete draining before removing a pump for maintenance. This enhances operator safety and minimizes any spilled liquid on-site.
Lastly, some customers required custom-machined flush and/or suckback grooves to promote a small amount of flow behind the rotor to prevent materials like latex or chocolate from setting up there. The new casings feature drilled holes from the suction and discharge ports to the area behind the rotor, plugged with removable setscrews as standard, to allow users to experiment with the best combination of flush and/or suckback if needed.
