Moyno 3913320100 Cast Iron Buna-N Stainless Steel Progressive Cavity Pump

The Moyno 3913320100 is a new, factory-assembled and USA-inspected progressive cavity (PC) pump — a pump type that moves fluid by means of a helical rotor turning within a double-helix elastomeric stator, producing a smooth, non-pulsating flow suitable for shear-sensitive, viscous, or abrasive media. Per the product label and the user-supplied product description, wetted construction consists of a cast iron pump casing, a Buna-N (NBR) elastomeric stator, a stainless steel rotor, and a carbon/mechanical face seal, with a wobble-style (flexible) drive shaft connecting rotor to drive shaft stub — the stub output shaft visible in the photos is bare stainless steel, designed for direct coupling to a drive or gearmotor. The 3913320100 model number places this unit in Moyno's compact 33 Series (33-prefix in the order number 5474845-6 33201, visible on the label), sized for lower-flow industrial applications including metering, chemical dosing, wastewater treatment, food processing (non-food-grade Buna-N), and OEM skid integration where a motorized drive is supplied separately. Moyno is an NOV brand, and this unit was assembled and inspected in the USA, as stated on the factory nameplate label; port caps and "Do Not Run Dry / Do Not Shut Off Discharge End" warning tag are still in place, confirming the unit is unused and new.
