Danfoss Spare Parts — Frequently Asked Questions
How often do Danfoss APP pumps need spare parts?
Under normal SWRO duty: O-ring kit annually, seal kit every 8,000–12,000 operating hours (typically every 12–18 months for 16 hr/day operation), valve kit every 20,000–40,000 hours, and major overhaul (piston/shoe, cylinder barrel) at 50,000+ hours. Poor pretreatment dramatically accelerates seal and valve wear.
What's the difference between a Danfoss seal kit and a repair kit?
A Danfoss seal kit includes the high-pressure shaft seals and wear rings — the most common consumable on APP pumps. A full repair kit additionally includes O-rings, valve plates, gaskets, and sometimes piston/shoe components for a complete pump rebuild. For typical service, the seal kit is sufficient; for major overhaul (50,000+ hours), order the complete rebuild kit.
How do I identify my Danfoss part number?
Every Danfoss APP pump has a stainless nameplate with the model (e.g., APP 5.1), the ordering code (180B3005), and the production date. Match the ordering code in our catalog to find the exact-fit spare parts. Email us a photo of the nameplate if you're not sure and we'll identify it for you.
Can I install Danfoss spare parts myself?
Basic service items (O-ring kit, seal kit) are routinely installed by site maintenance technicians following the Danfoss service manual. Major overhaul (piston/shoe, swash plate, drive shaft) requires precision torque specifications and clean-room handling — typically returned to a Danfoss-authorized service center. We provide service documentation with every kit and can arrange factory training if needed.
How much does a Danfoss seal kit cost?
Danfoss seal kits range from approximately $150 for small APP models (APP 0.6 to APP 3.5) to $1,200+ for large APP and PAH industrial models. iSave seal kits are typically $300–$800. We provide formal quotes within 4 hours of receiving your pump model and part need.
Do you ship Danfoss spare parts internationally?
Yes. We ship Danfoss spare parts worldwide. For shipments within the EU, parts dispatch direct from our Denmark warehouse with 1–3 day delivery. For North America, we ship from California with overnight available. For other regions, we coordinate factory direct shipment or US-warehouse air freight with documented chain-of-custody.
Are these genuine Danfoss parts or aftermarket?
100% genuine Danfoss factory parts, with full Danfoss factory warranty. ForeverPure has been an authorized Danfoss High Pressure Pumps distributor since 2003. We do not sell aftermarket equivalents — only OEM parts traceable to Danfoss production records.
