ITT Goulds Pumps
NM 3196 i-FRAME FRP Process Pumps
The Goulds NM 3196 i-FRAME is a non-metallic ANSI process pump whose casing and impeller are molded from fiberglass-reinforced vinylester (FRP). Solid corrosion-resistant construction throughout, not just a lining, gives it metal-like strength with superior resistance to aggressive chemicals.
Product Benefits
- No lining to fail: Because the FRP is solid rather than a coating, there is no lining to blister or breach: the entire wetted structure is the corrosion barrier.
- True volute efficiency: The casing is molded with a true volute, so hydraulic efficiency stays close to that of a metal pump.
- Positive torque transfer: The fully open impeller carries a non-wetted Hastelloy-C insert for positive torque transfer without exposing metal to the pumpage.
- Proven i-FRAME power end: It rides on the same i-FRAME power end as the metal 3196 family, with back pull-out construction and external impeller adjustment.
- Easy upgrade path: Dimensional interchangeability with the Goulds 3196 makes it a straightforward upgrade when a metal pump keeps corroding in place.
Where It's Used
- Severe corrosive services: The NM 3196 was designed for the full range of severe corrosive services in chemical processing.
- Mill chemical duties: In pulp and paper mills, typical duties include sulphate liquors and sodium sulphite, chemistries where non-metallic construction pays off in service life.
- Corrosion-proof alternative: Fluindo supplies this pump for the pulp and paper industry as a corrosion-proof alternative for chemical transfer around the mill.
Good to Know
- Low-temperature fit: FRP construction is best suited to relatively low-temperature services; hot duties call for a lined or alloy pump instead.
- Seal arrangements: Options include a single cartridge with backplate extension, a single outside seal with clamped seat, and conventional single or double seals with a seal chamber extension, all with a non-wetted FRP gland.
- Simple installation and spares: ANSI standard dimensions and parts interchangeability with the Goulds 3196 keep installation and spares management simple.
- Standard coupling guard: An ANSI B15.1 coupling guard is standard.
