During climb out through approximately 13000 ft we got a left hydraulic pressure low light/warning. After accomplishing the QRH procedure for said warning it was determined that our left engine hydraulic pump had failed. After review of the circumstances and possibility of xfer pump failure ie; left hydraulic system loss I declared an emergency (overweight landing) and returned. ZZZ dispatch was contacted and he consulted with maintenance and I was later told that both concurred with my decision. We landed uneventfully at ZZZ at a weight of 138200 pounds; sink rate of 300 FPM and the landing was smooth.
