New Solutions Added to Demeca Oy’s Product Portfolio
Demeca Oy has signed an agreement with HKP‑Koneet Oy, under which the piston pumps developed by HKP‑Koneet – including all accessories and product rights – will transfer to Demeca’s ownership and product range. Going forward, Demeca will be the manufacturer, marketer, and seller of these products.

The agreement was sealed with a handshake between the companies’ CEOs, Sakari Vinkki (Demeca Oy) and Markus Salonpää (HKP‑Koneet Oy).
Markus Salonpää, CEO of HKP‑Koneet Oy:
We specialize in manufacturing slurry‑handling equipment for agriculture and biogas plants. The piston pump is a concrete example of our expertise: a durable solution that minimizes operational challenges and costs. As promised, our products are designed for Finland’s harsh conditions. We now have a top‑tier product ready for deployment anywhere in the world, which is why this is the right time to move from development to commercial operations.
We believe Demeca is the right player to continue the commercialization we have initiated.
