Figure 7: Specification for maximum static pressure of pump head LPP-200.1/11
- Pressure limits only valid for pump head mounted on motor.
- Pump head LPP-200.1/11 comes delivered with PVDF mounting screws.
- Stainless steel screws with PTFE coating can be ordered separately according to Table 4.
It is recommended to use stainless steel (SS) pump head screws, which are available as an accessory (see
Table 4), at higher liquid temperature or when hammering effects (dynamic static pressure peaks) are
expected, which might result in longer term deformation effects of the standard PVDF screws.
