At a Glance:
Fits pump: HOMA GRP19/3 (Barracuda series, 2 HP grinder)
Form: Mechanical seal, supplied with lip seal
Lip seal: 20 x 35 x 7 mm (20 mm shaft, 35 mm OD, 7 mm width)
Applications
The HOMA GRP19/3 is a 2 HP submersible grinder pump from the Barracuda series, used on pressure sewer and low-pressure collection systems where solids have to be cut before they are pumped. Grinder duty is hard on seals — the cutter loads the shaft and the fluid carries whatever went down the line — so the seal and the lip seal behind it are the two parts that decide how long the rebuild holds. This assembly is a direct-fit aftermarket replacement, supplied with the 20 x 35 x 7 lip seal so the shaft is sealed properly on reassembly rather than reusing a hardened one.
Fits: HOMA GRP19/3 submersible grinder pump, 2 HP (Barracuda series). Includes the 20 x 35 x 7 mm lip seal — that is the lip seal dimension,
not the mechanical seal size.Working from the pump rather than a part number? Text a photo of the nameplate and the old seal to 561-414-1046 and we’ll confirm the match before you order. No purchase required.
