GROCO Pump Service Kit f/SPO Series Pumps - After 9/2001

The GROCO Pump Service Kit for SPO Series Pumps (manufactured after September 2001) is a comprehensive maintenance package designed to restore full operational capacity to aging or worn GROCO marine and industrial pump systems. This master service kit contains all critical internal wear components needed to renew pump performance without requiring complete unit replacement.

The kit includes a precision 8-slot rotor (SP-99-A), eight replacement blades (SP-98), an elastomer O-ring seal (2-034), a stainless steel snap ring, and a complete seal assembly (69089). These components address the primary failure points in reciprocating pump systems—rotor wear, blade degradation, and seal deterioration—which collectively cause pressure loss, reduced flow rate, and eventual operational failure. By replacing these core elements rather than the entire pump housing, operators extend equipment life while minimizing downtime and capital expenditure.

This service kit is intended for marine vessel operators, commercial fishing fleets, industrial facilities, and mobile service technicians who maintain GROCO SPO series pump installations. The kit is compatible exclusively with SPO pumps manufactured after September 2001, ensuring proper fit and seal integrity. Compact packaging (5 × 1 × 7 inches, 0.1 lbs) makes it suitable for vessel storage, field service vehicles, or spare parts inventory.

GROCO pump products are engineered for continuous-duty marine and industrial applications where reliability under sustained pressure cycles is non-negotiable. The SPO series represents the manufacturer's standard positive-displacement pump line, widely deployed in saltwater cooling systems, deck washdown systems, and auxiliary engine circuits aboard commercial and military vessels.
