PROCON
Frequently asked questions
Common questions about PROCON from 3G Electric.
What materials are used in PROCON rotary vane pump bodies?
PROCON rotary vane pump heads are available with either stainless steel or low-lead brass bodies. Stainless steel models offer corrosion resistance for applications involving water or mild chemicals, while low-lead brass versions are commonly specified for potable water and carbonation systems where lead content must be minimized. Both materials are machined to precise tolerances to ensure consistent vane sealing and long service life.
Are PROCON pumps NSF 169 listed?
Many PROCON rotary vane pump heads carry NSF 169 listing, which certifies compliance with standards for commercial carbonation equipment. This listing applies to models used in beverage dispensing systems where the pump contacts carbonated water or syrup. Buyers should verify the specific SKU's listing status; 3G Electric's product pages indicate NSF 169 listing where applicable.
What types of relief valves are available on PROCON pump heads?
PROCON pump heads are equipped with either balanced or standard relief valves. Balanced relief valves maintain consistent pressure regulation regardless of inlet pressure fluctuations, making them suitable for systems requiring stable output. Standard relief valves provide overpressure protection at a fixed set point. The valve type is specified in the product model number and datasheet.
Do PROCON pump heads include a strainer?
Some PROCON models include an integrated 120-micron strainer, while others do not. Models with strainers are identified in the product specifications; for example, low-lead brass versions often include a strainer, whereas stainless steel models may not. If a strainer is not included, an external inline strainer should be installed upstream to protect the pump from debris.
What is the maximum flow rate range for PROCON rotary vane pumps?
PROCON rotary vane pump heads offered by 3G Electric cover flow rates from 25 gph to 190 gph at standard operating speeds. The specific flow rate depends on the model and motor speed. Higher-flow models, such as the 190 gph version with 1/2" NPT ports, are suited for larger carbonation systems or water transfer applications, while lower-flow models are used in compact dispensing equipment.
Can PROCON pump heads be used with different motor types?
PROCON direct-drive pump heads are designed for coupling to standard electric motors via a shaft adapter or coupling insert. 3G Electric supplies coupling inserts and motor clamps to facilitate mounting. The pump head does not include a motor; buyers must select a motor with appropriate horsepower and shaft size to match the pump's flow and pressure requirements.
