Re: So I built a hydraulic pump today
			 
			 
			
		
		
		
			
			Reg,  Don't you think that without flow that pump would be expected to generate a lot of heat and might not last long . Some type of open center solonoid valve or a relief valve would be the cure and I think the pump performance would be even greater than what you  observed due to the cooler oil temp. You are on the right track with your design, Good JOB!   Fred
