Fill‑Rite KIT120RKG Rotary Pump Rebuild Kit for FR/SD Series — 2‑Bolt Rotor Cover, Shaft Seal & Vanes

The Fill-Rite KIT120RKG is a complete rotary pump rebuild kit that replaces worn internals and includes a versatile 2‑bolt rotor cover to restore dependable fuel transfer on compatible FR and SD series pumps.

If your FR1200, FR2400, FR4200, FR4400, FR600, SD1200 or SD600 G or H Series pump is showing signs of reduced flow, leakage, or general wear, the KIT120RKG supplies the factory‑spec parts to bring performance back without a full pump swap. This genuine Fill‑Rite kit gathers the essential seals, vanes, gaskets, O‑rings and rotor components needed for routine servicing in agricultural, commercial, fleet, and automotive fueling environments. The included 2‑bolt rotor cover is engineered to fit both 2‑bolt and 4‑bolt housings, simplifying repairs across multiple pump models.

How will this kit improve a pump that’s slipping or leaking?

Replacing the internal wear items in a rotary hand pump addresses common failure points: compromised seals, worn vanes, and degraded gaskets. Installing fresh components restores tighter tolerances and reduces internal bypassing that causes slipping and leaks.

• New shaft seal kit and O‑rings stop external and internal leaks.
• Bronze vanes and a refurbished rotor restore pumping efficiency.
• Rotor cover gasket and inlet screen help preserve correct flow and prevent debris damage.

Which pump models and fuels is KIT120RKG compatible with?

The kit is designed specifically for Fill‑Rite FR1200, FR2400, FR4200, FR4400, FR600 and SD1200, SD600 G & H Series rotary hand pumps. It services pumps used with common petroleum fuels, but always confirm compatibility with your pump serial/model and fuel type before installation.

• Listed Fitment: FR1200, FR2400, FR4200, FR4400, FR600, SD1200, SD600 (G & H Series).
• Typical fuels: gasoline, diesel, kerosene, and similar petroleum‑based fluids (verify specifics first).
• Includes parts to adapt between 2‑bolt and 4‑bolt rotor cover housings for flexible fit.

What parts are included and what do they each do?

The KIT120RKG bundles all critical internal wear pieces so you get a complete refresh in a single service operation. Each item replaces a component that commonly deteriorates with regular use in fuel transfer tasks.

• Rotor and rotor key — reestablish rotation and alignment for consistent flow.
• Bronze vanes — create pumping chambers that move fuel efficiently.
• Shaft seal kit, O‑rings, gaskets — restore sealing surfaces to prevent leaks and internal bypass.
• Rotor cover, cover bolts, inlet gasket & screen, bypass valve/spring — ensure correct cover mounting, debris protection, and pressure relief operation.

How does using this rebuild kit compare to replacing the entire pump?

Choosing a rebuild kit is typically faster and more cost‑effective than full pump replacement when wear is limited to internal parts. It preserves the existing housing and drive components while renewing the items that most affect flow and sealing.

• Lower cost than a new pump while restoring core functionality.
• Reduced downtime—service with commonly available hand tools in the field or shop.
• OEM‑spec parts maintain correct fit and performance characteristics.

Who is this for: The Fill‑Rite KIT120RKG is aimed at technicians, fleet managers, farmers, and service professionals who maintain FR and SD Series rotary hand pumps and prefer an OEM rebuild solution. It’s ideal for preventive maintenance or repair when pumps still have sound housings and drive assemblies but need the worn internals replaced to regain reliable fuel transfer performance.
