ÑÎ-150[À] units can be used as mortar pumps.
Their output rates are too high (0.36 to 0.72 cub.m/hr) when in
a standard configuration, which makes them unsuitable for manufacturing
small features or undersized products without adjusting the output
rate. N.S.T. has solved this problem by completing the standard
unit with an electronic speed-drive motor controller that can smoothly
adjust the output rate for small-size GRC product manufacture.
When only shotcreting is required (i.e. applying GRC as a protective
render), one doesn’t have to reduce the mortar pump capacity.
The compressor discharge directly depends on
the mortar pump output rate. When the mortar pump capacity is between
0.6 and 0.72 cub.m/hr, the compressor flow rate must not be less
than 3.5 cub.m (in case of PKS 3.5, for instance). Stationary electrical
compressors are heavy-weight (about 700 kg). Portable compressor
can be both electrical and diesel-driven, but they are more expensive.
High capacity is not essential for a stationary
compressor in case of production of small-size items. When the mortar
pump output is low (less than 0.24 m3/hour), one may use a compressor
with a capacity as low as 2000 l/min, e.g. a K-3 compressor.
