More outline: From now on out of previous 13 pumps only 11 remain in the performance list
What has changed in detail: The pump programme has been tightened, unified and has become easier. Out of the previous 13 pump types in the performance list only 11 remained, with no losses but optimisation. The current M-Head has been omitted without the loss of versatility in the available options. The MCH-Head was re-named as M, because it replaces the old M-Head. The MC-Head becomes M2-Head. The new M-Head and M2-Head will be available in any performance level with plate valves and soft valves. With the changeover all heads were re-engineered with the objective to achieve lower NPSH-values and thus avoiding cavitation. Furthermore the gear boxes have been revised, with higher performance inputs resulting in generally increased performance level.
New conversion kits not needed, pump-heads smaller and lighter in weight from now on
From now on the heads are smaller in their design size and thus lighter in weight. The good news: New replacement sets are not needed and all previous mounting parts still fit. According to the manufacturer the gear geometry and intersection stayed the same too. A1- and A2-Head remain the same, just with standardisation of the suction hoses. The benefit to the customer is next to flexibility very clearly the NPSH optimisation with lower values. Furthermore, in each design size there is the opportunity to customise the valve design size depending on the fluid distributed. The integrated oil coolers remain available for the mining industry.
The changes at a glance:
K40000-3G / 400 kW -> Upgrade to K45000-3G/ up to 450 kW
K50000-5G / 530 kW -> Upgrade to K55000-5G/ up to 550 kW
K80000-5G / 800 kW -> Upgrade to K100000-5G/ up to 1000 kW = 1 MW
K120000-5G / 1200 kW -> Upgrade to K150000-5G/ up to 1500 kW = 1.5 MW
Pump Heads (A- and M-Head)
MCH-Head becomes M-Head MC-Head becomes M2-Head
Both heads can get either plate valves or soft sealing valves.
