Core deposit may be withheld if the reservoir on your core arrives broken or the aluminum ring around the motor has been crushed beyond repair. Please wrap the pump in absorbent material and put plastic bags around it, buffer your parcel well inside, ideally double-box, and tape up well.

Ships within the US via FedEx 2-Day Service for $20, or internationally for $90 to most countries.

(International shipments are packaged tightly but safe, so that we can use a FedEx Flat Rate package. The pump ships without the black plastic motor cover in international shipments - re-use your original one)
