  We apply a microcanonical statistical model to investigate hadron production
in pp collisions. The parameters of the model are the energy E and the volume V
of the system, which we determine via fitting the average multiplicity of
charged pions, protons and antiprotons in pp collisions at different collision
energies. We then make predictions of mean multiplicities and mean transverse
momenta of all identified hadrons. Our predictions on nonstrange hadrons are in
good agreement with the data, the mean transverse momenta of strange hadron as
well. However, the mean multiplicities of strange hadrons are overpredicted.
This agrees with canonical and grandcanonical studies, where a strange
suppression factor is needed. We also investigate the influence of
event-by-event fluctuations of the E parameter.
