The 30-year old striker, who scored 30 goals in 43 Championship appearances last season, netted his first Premier League goal when converting from the penalty spot in the weekend's 1-1 draw with Swansea City.
It was just his third outing since returning from a nine-month absence with a knee injury and Eagles boss Pulis is hoping he can continue to get amongst the goals to help the south Londoners push further away from the relegation zone.
"It's great for us," Pulis said of Murray's goal.
"Goalscorers are streaky and he's got his first goal now, so you're hoping he gets four or five goals from now until the end of the season. We'll need them.
"He's been getting in at nine and finishing at four or five for six or seven months and the kid has been desperate to play in the Premiership.
"To get the injury and then for the club to get promoted and for him to get left out of all the rigmarole that goes with playing in the Premiership was obviously a big disappointment for him, but he's worked tirelessly and he deserves it."
