The price of a Monarch hydraulic pump ranges from about $300 to $1,000, as of 2015. The price of the pump depends on the model and its specifications.
Monarch hydraulic pump Assy M-3554-0107 with a 12-volt Dyna Jack costs an average of $600 while Monarch hydraulic pump Dyna Jack M-304-0284 costs about $400. The difference in the price is due to the differences between the models.
Specifications of the pump also affect its price. A Monarch PU3593LRV has a four-way to three-way function with a triple filtration, while the Monarch Dyna Jack 3519 has a two-way external position valve with a single-acting cylinder circuit. Because the PU3593LRV has more advanced specifications, its price is higher.
