FAQ
What liner sizes does DLSY stock under the W2214 program?
For F-1600 fluid ends we carry liner seals in 5 in, 5-1/4 in, 5-1/2 in and 5-3/4 in; for 12T-1600, zirconia liners in 5 in, 5-1/2 in and 5-3/4 in; for E-2200, zirconia liners in 7-1/4 in and 7-1/2 in plus an 8 in Grayloy liner; and for 9T1000, a 5-1/4 in zirconia liner.
Are pistons available as well as liners?
Yes. The program holds 37 piston items alongside 21 liner items — including a 7-3/4 in dual-duro piston for E-2200-class fluid ends — so liners and pistons can be ordered as a matched set.
Are W2214 parts original or aftermarket?
They are Southwest-type aftermarket replacements cross-referenced to the F-1600, E-2200, 12T-1600 and 9T1000 pumps, giving a cost-effective sourcing option without naming a single pump brand.
Which liner material should I choose?
Zirconia liners suit abrasive, high-wear service, while Grayloy is a proven general-duty option. Pairing a fresh liner with a new liner seal and a correctly sized piston gives the most predictable run life.
Can DLSY ship W2214 liners and pistons internationally?
Yes. We export to Canada, the United States and international oil & gas markets under HS code 84139100, with delivery schedules confirmed per order.
