The Proteas batsman scored 53* off 27 balls (two fours, four sixes) as the Sunrisers posted 197-6.
Aiden Markram’s men then restricted the Capitals to 188-6.
Mitchell Marsh returned bowling figures of 4-27 including a maiden over and then hit a 39-ball 63 but the effort was not enough for bottom-placed Delhi, who fell to their sixth loss in eight matches.
Former champions Hyderabad, who won their only title in 2016 under current Delhi skipper David Warner, bounced back from their three losses to move up one spot to eighth.
He is striking them clean and with some KLAAS 🔥🔥
Heinrich Klaasen is unbeaten on 43*(22) as @SunRisers reach 179/6 👌🏻👌🏻

Warner fell for a two-ball duck but Delhi’s chase looked good during a 112-run second-wicket partnership between Phil Salt, who made 59, and Marsh.
Hyderabad hit back with three wickets in three overs through their spinners and once Salt and Marsh departed the chase lost track.
Rising Indian leg-spinner Mayank Markande stood out with figures of 2-20 including getting Salt, a wicketkeeper-batsman from England, caught and bowled.
The batsmen set up victory after left-hand opener Abhishek Sharma smashed 67 off 36 balls after Markram won the toss and elected to bat first.
Hyderabad seemed to slip after they lost a few wickets but Klaasen, who struck his first IPL half-century, put on a couple of partnerships including a sixth-wicket stand of 53 with Abdul Samad to boost the total.
