Can We Build a Viking® GG4195-Style Internal Gear Pump? Yes – This Is the Kind of Pump We Make

This is the kind of pump we build — a Viking® GG4195 internal gear pump, complete with casing, internal gear set, shaft and bearings. When a customer brings us a reference pump like this, we can manufacture the same type of unit in our workshop.

The GG series is Viking®'s heavy-service internal gear pump line: asphalt, lube oil, hot oil, bitumen and chemical media — frequently viscous, frequently at elevated temperature. The internal gear design handles high-viscosity flow smoothly with low pulsation, and the cast construction is built for long service life in continuous duty.

Whether you're replacing a worn unit, kitting out a new process, or need a pump that matches a specific Viking®-style design, we can build it — dimensioned to your shaft size, port configuration, and duty requirements, and assembled as one complete working unit.

And if you already have a pump running in your plant, the fastest route is even simpler: send us the sample. Customers regularly ship us a used pump or a drawing, and we reverse-engineer it in our workshop — matching the shaft size, port configuration, and seal envelope — then build the replacement unit. The same applies to the seal end: as a manufacturer of mechanical seals for rotating equipment, we can supply the matching mechanical pump shaft seals, mechanical seal replacement parts, or OEM replacement mechanical seals alongside the pump itself, so you get the whole spare package from one supplier.

Send us your sample — a pump, a drawing, or a worn-out unit — with your process conditions, and we'll come back with a proposal: the specifications we would build to, the seal options, and the lead time.
