All the current political parties in South Africa have pictorial emblems or logos. So did many of the earlier parties, of the "old", i.e. pre-1994, South Africa.
Only one appears to have adopted a coat of arms, namely the Herstigte Nasionale Party ("Re-established National Party"), which broke away from the mainstream National Party in 1968. Its arms, in the colours of the old national flag, depict three powder-horns - a nationalist symbol - inscribed with significant dates in Afrikaner nationalist history.Many parties have flags, some of which are registered at the Bureau of Heraldry. You'll find a detailed discussion and illustrations on the Flags of the World website.
