When someone is trying to pump a stock and create demand they print a large buy order to try to stimulate demand and get others to buy and drive the stock price up. To pump a stock effectively however there needs to be a story or at least some scrap of info people can latch onto. In the case of EIPC there is absolutely nothing. The fact that the issue has a relatively low float allows it to be manipulated but again with no underlying news or even rumor a pump can't be maintained.
