Cri-man PTH Chopper Pump Supports Efficient Slurry Spreading

With the increasing demands of Low Emission Slurry Spreading Equipment (LESSE) regulations, efficient slurry management is more important than ever. The Cri-man PTH Chopper Pump has emerged as a reliable solution for farmers and contractors, helping to improve slurry distribution while meeting environmental standards.

Meeting LESSE Requirements

LESSE aims to minimise ammonia emissions and prevent pollution while ensuring that slurry provides maximum nutrient value to the soil. According to data from the Department of Agriculture, Environment and Rural Affairs (DAERA), slurry must be properly chopped to ensure even distribution and reduce ammonia discharge.

Research shows that traditional Shoe Plate distribution has the weakest performance in controlling ammonia emissions. In contrast, Trailing Hose, Trailing Shoe, and Shallow Injection methods perform significantly better, provided the slurry is adequately chopped. LESSE systems can reduce nitrogen loss by up to 60% and cut ammonia pollution by 70-80% when using Shallow Injection methods.

Given these requirements, many contractors now use LESSE spreading systems, making pre-chopping an essential step in slurry management. Proper pre-chopping helps prevent blockages in applicators and ensures even distribution onto the ground.

The Cri-man PTH Solution

The Cri-man PTH Chopper Pump has proven to be a highly effective solution for slurry handling. Steve Marchant of S W Marchant Agri Limited in Kent shared his experience:

“We have used various pumps for years and always found that because the pump would pass larger lumps of manure, the macerator on the applicator could frequently block. Since moving to the Cri-man PTH Chopper Pump from T-T, we have noted minimal disruption to the operation. This allows us to concentrate on the job in hand.”

Beyond its solids-handling capability, the Cri-man PTH Chopper Pump also delivers strong performance at reduced RPM, increasing pressure and flow while cutting fuel costs—an added advantage for agricultural contractors.

With LESSE regulations shaping the future of slurry spreading, the Cri-man PTH Chopper Pump provides an efficient and reliable solution for farmers and contractors looking to optimise their operations while reducing environmental impact.
