Simplex Hand Pump and Cylinder Selection Guide

Product Line Overview

Wide Variety

Simplex offers the widest selection of hand pump styles, reservoir sizes, and flow rates to meet your everyday needs. Each pump has specific features that make certain models better suited for particular jobs. Select a hand pump with features that best fit your application.

Lowest Handle Effort

Simplex hand pumps have low, back saving handle efforts to reduce operator fatigue & back injury.

Built for Rugged Industrial/Construction Use

Shipyards, steel mills, construction sites and weld shops can be rough environments for hand pumps. Simplex’s all metal and aluminum designs withstand real world conditions and applications.

Optimal Oil Displacement Per Stroke

More oil per stroke means less handle strokes per job. Simplex pumps have the highest available oil displacement per stroke, in many cases reducing the number of handle strokes as much as 50%.

Total Control of Hand Pump Operation

Simplex release valves have a fine pitch screw and large valve handle for maximum control. Check ball valve design is more reliable than needle valves, and less costly to repair.

Easy To Use / Built To Last

Pivot linkage provides uniform handle effort at all points along the arc of the pump handle stroke. The pivot reduces piston side loading for longer pump life. Some pump models have four-way valves for use with double-acting cylinders.

PROPER SIZE SELECTION

Portable Hand Pumps

Single & two speed compact hand pumps deliver a constant flow to smaller cylinders or hydraulic powered tools regardless of load. Ideal when durability as well as portability are important.

Aluminum Hand Pumps

Aluminum hand pumps are the perfect choice when a light weight pump is required. The alloy construction resists corrosion and stands up to heat, welding sparks and other environments where composite pumps may not be suited.

Heavy Duty Hand Pumps

Heavy duty, two speed hand pumps in the low pressure stage deliver a high volume of oil per stroke for fast cylinder speed. Once the load is engaged, the pump automatically switches to the high pressure stage.

Specialty Hand Pumps

Specialty hand pumps are perfect for OEM applications or as emergency backup pumps. The pumps were designed to fit in tight spaces and are ideal for fixed bolt down applications.

Hi-Flow Hand Pumps

Heavy duty hand pumps with 4 way valves are used to power doubleacting cylinders or tools.

Configured Sets

Standard hand pump and single acting cylinder configuration.

Sizing The Proper Hand Pump To Your Cylinder

Once you have selected your cylinder. find the required reservoir capacity in the cylinder specification chart. and choose a hand pump with at least 10% more reservoir capacity per cylinder.

Example

An R256 cylinder (page 11) has a required oil capacity of 527.6 cm3. The P42 hand pump (page 34) with a reservoir capacity of 737.4 cm3 can pump this cylinder to its full stroke. If two R256 cylinders are to be raised. use a P140 with a reservoir capacity of 2867.7 cm3 6.35 mm I.D. hose requires 32.2 cm3 oil per meter. 9.65 mm I.D. hose requires 69.9 cm3 per meter.

Type Of Cylinders

Once you have selected your cylinder. find the required reservoir capacity in the cylinder specification chart. and choose a hand pump with at least 10% more reservoir capacity per cylinder.

Hand Pump / Cylinder Speed Chart

Use this chart to determine the number of full pump handle strokes required to extend a Simplex cylinder 1" (25,4 mm). You may take handle stroke per 1" (25,4 mm) and multiply it by the cylinder stroke to determine the number of strokes required to fully extend the cylinder.
