Denison T6 cannot compare to VQ or VMQ for cold start-up conditions The unique flex plate design of the VQ allows for the increase in viscosity and pressure rise during cold start-up Different kits for right and left hand rotation on T6 (D and E frames) and T67 (C, D and E) KEY SELLING POINTS Shaft torque capacity is very limited on T6 and T67 pumps compared to VMQ - Denison state “be aware of shaft torque limits” Inlet restrictions also apply to Denison pumps - they sa
