Can anyone point me in the right direction for a replacement Grundfos circulation pump for an underfloor heating manifold?

I have a Grundfos USP0 15-65 130 Part number 96836743 which is a 1" bsp I believe. Looking to replace this and Grundfos says this is an OEM part which they cannot provide. Upinor, the manufacturer of the manifold, is quoting £388 plus VAT for a replacement WILO.

I have attached images of the pump and manifold for reference.

Thanks in advance!

Uponor are quoting £387.98 plus vat for a Wilo Yonos Para which seems ridiculous to me.

According to Grundfos who just came back to me, they make a UPS3 15-50/65 which is supposed to have 1" bsp threads. Having a quick scout around, all I can see are 1 1/2" threads for the UPS3.
The USP0 is the original pump that came with the Upinor manifold over 12 years ago, I assumed Uponor supplied as part of a kit.

Just swap the head ?
 
Unfortunately this isn't something we do, however it is a PU.110 Grundfos Pump 1" 15/60 15/65 which are now very rare as they're all 1 1/2".

@oxgman Do you know the Uponor Part Number? We supply Uponor items so could provide you a price.

Could they price up a new manifold as I would suspect it would be around the same cost small 3 zone system etc ?
