A dairy farm across the waters in Cheshire that was experiencing issues handling sand-laden slurry, has turned to a new pump and help in the set-up of its reception pit.
The 1,250-cow Woodhey Hall Farm was being forced to fix its slurry pump every week, as proprietor, Paul Robinson, explains:
“The seals on the pump kept failing, so it was taking up way too much time for us with repairs and maintenance.”
“In theory, it was a perfectly good pump for ‘slurry’, but we soon saw that for sand-laden slurry, it is a totally different story. You need a much sturdier pump, and the right set-up.”
To try and find the right solution for pumping the slurry from the reception pit up to the separator, Paul Robinson called in Landia.
He added that sand-bedding has its health advantages for the herd’s cows with less lameness, less need for anti-biotics, and in general, less dust.
But, he says, “you need to engage with a company who has the right kit and a proper understanding of how to handle what is a difficult, abrasive slurry”.
Landia worked closely with Woodhey Hall Farm to emphasise the need to keep the sand-laden slurry moving as quickly as possible and whilst as fresh as possible.
Paul Davies from Landia commented: “When a reception pit is too large, and the sand-laden slurry too spread out, a pump can easily become overwhelmed because the second stage of the process becomes far too heavy with sand.”
“It becomes almost as if trying to pump sandpaper, which not surprisingly, is very damaging to the pump.”
To make the system as efficient as possible, they installed the pump vertically, to minimise the contact made between the sand and the pump, though for sand applications, they always supply units with hardened components.
“The need for spare parts is inevitable in this application, but it is possible to minimise wear and protect against abrasion for as long as possible.”
Paul Robinson from Woodhey Hall Farm, continued: “The Landia pump just had not stopped since its installation.”
“We know we can call on them for advice if we need it, so it is good to have back-up. We have made significant savings, and overall, everything is much easier to handle.”
