Advantages of Specialized Feed Plunger Pumps for Filter Presses

Key Advantages:

1. High outlet pressure of the plunger pump: It can... maintain a pressure of 20 kg. Unlike screw pumps, which fail to maintain pressure as the stator and rotor wear (leading to insufficient feed pressure or excessively long feed time), this issue is avoided.
2. Low energy consumption: A 350 m² filter press is typically equipped with a 22 kW screw pump, and a 600 m² filter press with a 45 kW screw pump. In contrast, plunger pumps only require 18.5 kW and 22 kW respectively. Especially for 600 m² filter presses, energy consumption is reduced by more than half.
3. Low post-maintenance costs: For each screw pump unit, the rotor and stator need to be replaced every six months. According to market research, a set of stator and rotor for a 35 kW screw pump costs approximately 60,000 yuan. However, plunger pumps only require replacement of valve plates and rubber seals, with each replacement costing around 6,000 yuan. Its maintenance cost is only about 10% of that of screw pumps.
