Frequently asked questions
Common questions about MACNAUGHT from 3G Electric.
What types of fluids are MACNAUGHT drum pumps compatible with?
MACNAUGHT drum pumps are designed primarily for non-corrosive fluids such as oils, lubricants, and fuels. The wetted materials vary by model: carbon steel is common for suction tubes and internal components, while polypropylene and stainless steel are used in some nozzles (e.g., BP-HG). These materials are suitable for petroleum-based products but are not rated for aggressive chemicals or solvents. Always verify chemical compatibility with the specific model’s material specifications before use.
How do MACNAUGHT cordless battery-powered pumps compare to manual or air-operated models?
MACNAUGHT cordless pumps (e.g., BP205X-UNA) operate on 18 V batteries and are intended for portable, on-demand fluid transfer without external power or compressed air. They include a discharge hose and nozzle, with carbon steel suction tubes. Manual pumps require hand operation and are suited for lower-volume dispensing. Air-operated pumps (e.g., T312-02) offer higher flow rates (3.43 gpm) and handle higher viscosities (2,200 cps) but need a compressed air supply. The choice depends on available utilities, mobility needs, and fluid characteristics.
What is the maximum flow rate of MACNAUGHT manual dispense guns?
MACNAUGHT manual dispense guns have varying flow rates depending on the model. The non-metered BP-HG has a maximum flow rate of 1.5 gpm, while the analog metered HG40P-02 can handle up to 7.9 gpm. The B2-01 manual nozzle does not have a published flow rate but is designed for controlled dispensing. Flow rates are influenced by fluid viscosity and operating pressure; actual performance may differ from maximum ratings.
Are MACNAUGHT repair kits available for their drum pumps?
Yes, MACNAUGHT offers repair kits such as the BP-1K impeller and seal kit, which is compatible with hand-operated drum pumps (BOP series). This kit includes an impeller and seals to restore pump performance. 3G Electric stocks these kits to support maintenance of existing MACNAUGHT equipment. Always confirm the pump model and part number (e.g., BP-1K) to ensure compatibility.
What connection types are used on MACNAUGHT dispensing nozzles?
MACNAUGHT dispensing nozzles use either NPTF (National Pipe Taper Fuel) or BSP (British Standard Pipe) connections. For example, the B2-01 nozzle has a 1/4 in NPTF connection, while the BP-HG and HG40P-02 use BSP connections. Verify the connection type of your drum or pump outlet before selecting a nozzle to ensure a proper fit.
